In recent years, brand new vehicles equipped with muti-driving assist systems have been more and more popular. As a result, we propose a path planning design for muti-vehicle driving assist systems that enable vehicle adjust speed and traveling direction according to different road sections by itself. The overall system can be divided into two layers, one is decision layer and the other is control layer. In decision layer, reference route which built by high accuracy real time kinematic differential positioning system is necessary. Then, reference route would be separated into bending and straight sections. After that, desired speed and steering angle can be obtained by kinematics equations and position node of reference route. In control layer, actuators, such as throttle, braking paddle, and steering wheel, are driven by fuzzy logic controller to reach desired speed and steering angle from decision layer. The overall system is implemented on an electric golf car which as a testing platform. The experimental results show that the proposed system integrates kinematic and human experience to fulfill above functions.
近年来,配备多路驾驶辅助系统的全新车辆越来越受欢迎。因此,我们提出了一种多车驾驶辅助系统的路径规划设计,使车辆能够根据不同路段自行调整速度和行驶方向。整个系统可分为两层,一层是决策层,另一层是控制层。决策层需要高精度实时运动差分定位系统建立参考路线。然后,将参考路线分为弯曲段和直线段。然后通过运动学方程和参考路线的位置节点得到所需的速度和转角。在控制层,由模糊逻辑控制器驱动油门、制动桨和方向盘等执行器,使决策层达到所需的速度和转向角。整个系统以电动高尔夫球车为测试平台实现。实验结果表明,该系统将运动学和人的经验相结合,实现了上述功能。

Distributed Unknown Input Filtering for Systems with Unknown Inputs 未知输入系统的分布式未知输入滤波
Pub Date : 2018-06-01 DOI: 10.1109/ICSSE.2018.8520243

It is well known that, for model-free unknown input filtering (MUIF) the unknown inputs are generally reconstructed with a multi-step delay, which may yield multi-step delayed state and unknown input estimates. This certainly is unpractical for real-time state estimation problems. To solve this problem, the paper first proposes a distributed multi-step-delay state and input estimator (DMSDSIE) for a specific topology of network. Then, a real-time state estimator design of a certain MUIF application based on the DMSDSIE is developed. This research highlights a possibility to apply distributed filtering through a network to alleviate the time-delay estimation problem of a general simultaneous input and state estimation problem.
众所周知,对于无模型未知输入滤波(MUIF),未知输入通常是用多步延迟重构的,这可能会产生多步延迟状态和未知输入估计。这对于实时状态估计问题显然是不切实际的。为了解决这一问题,本文首先针对特定的网络拓扑结构提出了一种分布式多步延迟状态和输入估计器(DMSDSIE)。然后,开发了基于DMSDSIE的某MUIF应用的实时状态估计器设计。本研究强调了通过网络应用分布式滤波来缓解一般同步输入和状态估计问题的时延估计问题的可能性。

This paper proposes an adaptive control system for uncertain overhead cranes on the basis of hierarchical sliding mode approach combined with radial basis function (RBF) neural network. A sliding surface is defined by linearly combining two sub-manifolds. A RBF neural network is adopted to approximate the unknown dynamic model. The control law is designed to ensure the stability of sliding surfaces while an adaptation mechanism for updating weight matrices of neural network is derived from a candidate of Lyapunov function. Simulation results show the effectiveness of the proposed control scheme.

Characterization of Grinding Wheel Condition by Acoustic Emission Signals 用声发射信号表征砂轮状态
Pub Date : 2018-06-01 DOI: 10.1109/ICSSE.2018.8520249

The properties of grinding wheel condition for the hard and brittle material thinning equipment (Vertical Wheel Grinder) can be estimated based on the analysis of acoustic emission (AE) signals during grinding process. In this paper, a study on the frequency content of the raw AE signals is carried out to determine the features of frequency bands from three grinding wheels with different grades. The signal characteristics of the surface condition change affected by different wheel grades are obtained from the root mean square (RMS) and ratio of power (ROP) statistics at frequency bands selected from AE spectra. The analyze results indicate that the proposed methodology can distinguish different grades of grinding wheel condition from each raw AE signals segment using the ROP statistics. Thus, based on AE spectra analysis, the raw AE signals contain most of grinding information at the frequency bands of 600~900 kHz. Discrete wavelet transform and RMS statistics are able to describe the change of grinding-wheel-surface condition during grinding process. The findings of this paper proves that this research can be applied to the intelligent grinding monitoring systems in the future [1].
对硬脆材料减薄设备(立轮磨床)磨削过程中的声发射信号进行分析,可以估计磨削过程中砂轮状态的特性。本文对原始声发射信号的频率含量进行了研究,确定了三种不同等级砂轮的频带特征。从声发射光谱中选取频带的均方根(RMS)和功率比(ROP)统计量得到不同车轮等级对车轮表面状态变化的信号特征。分析结果表明,该方法可以利用机械钻速统计量从每个原始声发射信号片段中区分出不同等级的砂轮状态。因此,基于声发射谱分析,原始声发射信号在600~900 kHz频段包含了大部分磨削信息。离散小波变换和均方根统计能够描述磨削过程中砂轮表面状态的变化。本文的研究结果证明,该研究可以应用于未来的智能磨矿监控系统中[1]。

This study considers the use of Arduino to achieve state of charge (SOC) estimation of lithium-ion batteries by adaptive extended Kalman filter (AEKF). To implement a SOC estimator for the lithium-ion battery, we adopt a first-order RC equivalent circuit as the equivalent circuit model (ECM) of the battery. The parameters of the ECM will be identified through the designed experiments, and they will be approximated by the piecewise linear functions and then will be built into Arduino. The AEKF algorithm will also be programed into Arduino to estimate the SOC. To verify the accuracy of the SOC estimation, some lithium-ion batteries are tested at room temperature. Experimental results show that the absolute value of the steady-state SOC estimation error is small.

Social Networking Without Sacrificing Privacy 不牺牲隐私的社交网络

Social media is a De Facto standard in online communication. When users interact with others on a large scale, privacy plays an increasingly important part in maintaining safety and user confidence in a social media platform. Allowing end-users to control their interactions and data with others is a way to inspire end-user confidence. Many control schemes exist; however, they are flawed on two key points. These systems are somewhat confusing to the end users in that the users may not understand exactly what information is being shared with others and that the control schemes are hidden and abstract. In this project, we propose an idea with a prototype, named Solendar, that attempts to solve the issue with a special authorization approach. It has a pass system which allows end-users to explicitly specify which users are able to see and interact with their information on individual level. It has a group system that builds on the pass system, allowing end-users to organize other users into logical segments for effective information sharing while retaining the control of privacy.
社交媒体是在线交流的事实上的标准。当用户与他人进行大规模互动时,隐私在维护社交媒体平台的安全性和用户信心方面发挥着越来越重要的作用。允许最终用户控制与他人的交互和数据是激发最终用户信心的一种方式。存在许多控制方案;然而,它们在两个关键点上存在缺陷。这些系统对最终用户来说有些混乱,因为用户可能无法确切地理解与他人共享的信息,并且控制方案是隐藏的和抽象的。在这个项目中,我们提出了一个名为Solendar的原型的想法,它试图用一种特殊的授权方法来解决这个问题。它有一个通行证系统,允许最终用户显式指定哪些用户能够在个人级别上查看和交互他们的信息。它有一个建立在通行证系统基础上的组系统,允许最终用户将其他用户组织到逻辑段中,以实现有效的信息共享,同时保留对隐私的控制。

Although mobile robots have achieved great success in indoor navigation, they are still facing problems like operating through multi-floor hotel buildings. In this paper, a low-cost and lightweight mobile robot is proposed for hotel room service. For delivering any item that customers need, the robot should be able to manipulate elevators in an unmanned hotels. So, it is separated into three parts: elevator button detection, coordinate transform and fuzzy logical control to manipulate the robotic arm. To recognize and detect a variety of elevator panels and buttons, a large number of the images are collected and labeled manually by ourselves. With state-of-the-art deep learning framework, our model has achieved 95.172 mean average precision (mAP) even in elevators that are not included in training data. After properly detecting the elevator buttons, the 3D position corresponding to each elevator button is transformed by the fusion of two sensors which are a mono-camera and a Lidar. This paper presents a coordinates transform neural network to estimate real world position, and our method achieves in an average distance error of 1.356 mm. The fuzzy logical controllers are designed for manipulating the robotic arm fast and smoothly.
尽管移动机器人在室内导航方面取得了巨大的成功,但它们仍然面临着通过多层酒店建筑等问题。本文提出了一种低成本、轻量化的酒店客房服务移动机器人。为了运送顾客需要的任何物品,机器人应该能够操纵无人酒店的电梯。因此,将其分为电梯按钮检测、坐标变换和模糊逻辑控制三个部分来实现对机械臂的操纵。为了识别和检测各种电梯面板和按钮,大量的图像是我们自己手工采集和标记的。使用最先进的深度学习框架,即使在未包含在训练数据中的电梯中,我们的模型也达到了95.172的平均精度(mAP)。在正确检测到电梯按钮后,通过单摄像头和激光雷达两个传感器的融合变换每个电梯按钮对应的三维位置。本文提出了一种坐标变换神经网络来估计真实世界的位置,该方法的平均距离误差为1.356 mm。为了快速、平稳地控制机械臂,设计了模糊逻辑控制器。

Today, data in a vast number of social networks are abundantly utilized to help consumers make decisions in selecting products. While companies endeavor to analyze and interpret the multitude of customer opinions and sentiments, an accurate assessment becomes problematic. Many research studies encounter semantic conflicts of words or synonymous words, and errors occur within the SentiWordNet algorithm, when assessing both positive and negative words in some sentences. The present study, therefore, aims to solve the above-mentioned problems through DBpedia, and addresses the differences in word meanings, and to create a user interface for retrieving products in the form of keywords, in order to help consumers make decisions in selecting products. The efficiency measurement of sentiment analysis within the present study was 94%.

Household drugs or home medicines are normally nonprescription drugs that every family should prepare for relieving sickness. However, as our survey, many small households having 1–3 members in apartments or dormitories do not have a well preparation of necessary household drugs, and the worse is that some drugs have been expired. To this end, this work proposes an approach to the development of a nonprescription-drug vending machine in a residential building for serving home medicine to all residents in the building. We also introduce a smart way to order and get drugs using the inter operability of an application, a vending machine, and a server. The implemented prototype demonstrates that our approach is possible and feasible to serve a better service for accessing home medicines.

The implemented prototype demonstrates that our approach is possible and feasible to serve a better service for accessing home medicines.","PeriodicalId":431387,"journal":{"name":"2018 International Conference on System Science and Engineering (ICSSE)","volume":"172 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132044426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this paper is to illustrate the development process of a Wireless Charging Robot (WCR) according to scenario-based design approach. In the previous work, we have introduced the prototype design and its working functionality as a combination of state of the art in the field of wireless power transmission and mobile robotics. The prototype has designed and examined for various usage scenarios. This work is within our research on WCR where we are attempting to develop an advanced WCR design, considering the example of various practical scenarios for the smart environment. A mobile robot is equipped with a wireless charger and navigates in the environment of various battery nodes in order to charge the network in an efficient way. Hence, we present a mathematical model to find the shortest route for WCR. Furthermore, we also address the cultural influence and reactions of wireless charging robot with a survey result based on country sociological impact.
本文旨在阐述基于场景设计方法的无线充电机器人(WCR)的开发过程。在之前的工作中,我们介绍了原型设计及其工作功能,将其作为无线电力传输和移动机器人领域最新技术的结合。原型已经针对各种使用场景进行了设计和检查。这项工作是在我们对WCR的研究中,我们正在尝试开发一种先进的WCR设计,考虑到智能环境的各种实际场景的例子。移动机器人配备无线充电器,在各种电池节点的环境中进行导航,以高效地为网络充电。因此,我们提出了一个寻找WCR最短路径的数学模型。此外,我们还通过基于国家社会学影响的调查结果来解决无线充电机器人的文化影响和反应。
