Modeling Diesel Oxidation Catalyst Upstream and Downstream Exhaust Gas Temperatures Using LSTM RNN 基于LSTM RNN的柴油氧化催化剂上下游废气温度建模
M. Elhag, M. Selçuk Arslan
Sensors are essential in powertrain engineering and exhaust aftertreatment systems due to the increasing need for high performance and fewer emissions. Mostly in diesel oxidation catalysts, the upstream and downstream temperature sensors are attached to the vehicle until their models get calibrated then removed in the end-user version. The modeling process is both extravagant and time-consuming as it requires engine and chassis dynamometers. In fact, these temperature models are used in the monitoring of CO emission level and as inputs to calculate the other exhaust aftertreatment system components' efficiencies. The purpose of this paper is to investigate the use of long short-term memory networks in the automotive sector by generating a model for the diesel oxidation catalyst upstream and downstream temperatures as an example. Measurements from engine sensors and actuators position feedback were recorded from a vehicle and used as training and validation data. After sufficient training, the model was utilized to evaluate and predict the modeled oxidation catalyst upstream and downstream temperatures.
由于对高性能和低排放的需求日益增加,传感器在动力总成工程和排气后处理系统中至关重要。在柴油氧化催化剂中,上游和下游温度传感器通常安装在车辆上,直到它们的模型被校准,然后在最终用户版本中移除。建模过程既奢侈又耗时,因为它需要发动机和底盘测功机。事实上,这些温度模型用于监测CO排放水平,并作为计算其他排气后处理系统组件效率的输入。本文的目的是通过生成柴油氧化催化剂上游和下游温度的模型来研究长短期记忆网络在汽车行业的使用。从车辆上记录发动机传感器和执行器位置反馈的测量结果,并将其用作训练和验证数据。经过充分的训练后,利用该模型对模拟的氧化催化剂上下游温度进行评价和预测。

Low Voltage Power Quality Assessment using Smart Meters 使用智能电表进行低压电能质量评估
Jacques Wattel, U. Minnaar, Pieter Uys, J. Beukes
Power quality on South Africa’s low voltage networks is largely unmonitored and not well understood. Regulatory requirements in South Africa requires utilities to monitor power quality at every 1 in 20 000 customers. Smart grids and smart metering is an ever-evolving field with the number of smart meters rising rapidly. This paper introduces the concept of monitoring power quality parameters on the low voltage networks using smart meters. Utilizing smart meters to monitor power quality on low voltage networks will allow utilities to comply with regulatory requirements in a cost-effective way. In this paper an experimental meter is used to evaluate the capabilities of smart meters to perform Fourier transforms on voltage and current to calculate harmonics. Experimental results prove this capability.

Can Palaz, Emre Yönel
Hybrid electric vehicles (HEV) provide an acceptable compromise in the transition from fossil fuel based to electric based transportation while introducing additional complexity due to added degrees of freedom. In parallel, the increasing connectivity of modern vehicles contributes to the information available for decision making and controls. In this work, a predictive energy management strategy based around model predictive control (MPC) techniques is implemented and tested on model-in-the-loop (MiL) and hardware-in-the-loop (HiL) environments with models mainly derived with first principles. The components of the implementation, including the derivation of the prediction model, constraints, and selection of prediction horizon, are explained in detail. The factors that affect the prediction, i.e. elevation profile of the road ahead and velocity profile, and their effect to prediction are described. Finally, the differences between the MiL and HiL test results are analyzed.

B. Ali, N. Benalia, Nadia Zerzouri Nora
There is an exponential growth of solar photovoltaic technology for energy generation in comparison with the conventional and other renewable energy sources. Sun energy is the best option for power generation as it is available everywhere and is free to operate. Shading is one of the most important aspects that affect performances of PV systems. The first purpose of this paper is modeling and simulation of a five parameters photovoltaic cell and illustration of its electrical characteristics under standard test conditions (STC) and under environment condition variation using Matlab/Simulink software. The second purpose is to study influence of partial shading on the current-voltage characteristics and on output power of the PV system with and without bypass diode.

A Low Cost Manipulator Training Set 低成本机械手训练集
Saygın Ay, M. Kutay, Tuncay Ercan
Manipulators serve worldwide to increase quality requirements and speed up the production of the manufacturing industry. Typical applications of manipulators include welding, painting, ironing, assembly, picking and placing, product inspection. In this study, we focus on designing and implementing a low-cost training manipulator set for "Robotic and Control Laboratory" in the University. The set includes two 6-DOF manipulators controlled in coordination by Raspberry PI computer using Codesys platform. Manipulators can move to the desired coordinates through forward kinematic calculations The link transformation matrices for each joint are obtained by the Denavit-Hartenberg (DH) conventions. Due to complexity of transformation matrices, Matlab program is used to solve the matrix equations and the calculation results are transferred to Codesys environment. Codesys control application creates a virtual PLC functionality for Raspberry PI that communicates with servo control board by I2C communication protocol. Servo control board generates Pulse Width Modulation (PWM) signals applied to servo driver motors for obtaining the desired movements. In order to ease the user-manipulator interactions, a web-based interface is developed for running on a tablet PC or smart phones. Students use the set successfully for various practices in the laboratory.
机械手服务于世界各地,以提高质量要求,加快制造业的生产。机械手的典型应用包括焊接、喷漆、熨烫、装配、取放、产品检验。在本研究中,我们重点设计并实现了一套低成本的训练机械手,用于大学“机器人与控制实验室”。该装置包括两个六自由度机械手,由树莓派计算机利用Codesys平台进行协调控制。通过正运动学计算,机械手可以移动到期望的坐标,每个关节的连杆变换矩阵由Denavit-Hartenberg (DH)约定得到。由于变换矩阵的复杂性,采用Matlab程序求解矩阵方程,并将计算结果转移到Codesys环境中。Codesys控制应用程序为树莓派创建了一个虚拟PLC功能,通过I2C通信协议与伺服控制板通信。伺服控制板产生脉冲宽度调制(PWM)信号,应用于伺服驱动电机,以获得所需的运动。为了简化人机交互,开发了一种基于网络的界面,可在平板电脑或智能手机上运行。学生们成功地在实验室中进行了各种实践。

Bendjillali Ridha Ilyas, Beladgham Mohammed, M. Khaled, Abdelmalik Taleb Ahmed
To recognize and automatically identify the identities of individuals, there are several biometric identification systems based on physiological and behavioral characteristics, in our work we are interested in face recognition, which is a recent biometric authentication technology. This technology offers a reasonable level of precision. In this paper, we propose a method of biometric recognition of a person by their face using the wavelet transform. For our application, we have opted for different types of wavelets in order to decompose the region of interest. The evaluation and judgment of each type in relation to the other is given by the calculation of the parameters Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). The experimental results were performed using the FEI database.

Adaptive Fourier Linear Combiner based on Modified Least Mean Kurtosis Algorithm 基于改进最小均值峰度算法的自适应傅立叶线性组合器
Engin Cemal Menguc
In this study, we propose an adaptive Fourier linear combiner (FLC) based on a modified least mean kurtosis (LMK) algorithm for canceling the sinusoidal noise signals from the desired signals. In the proposed framework, the weight coefficients of the FLC are adjusted by using the modified LMK algorithm instead of the conventional least mean square (LMS) algorithm. The fundamental reasons for using the proposed LMK algorithm in the FLC are that it provides a fast convergence rate, a lower steady-state error and a robust behavior against sinusoidal noise distributions. The performance of the proposed FLC algorithm is assessed on the noise canceling problem by comparing that of the conventional FLC based on the LMS algorithm. The simulation results demonstrate that the proposed FLC based the modified LMK algorithm outperforms its conventional LMS algorithm in terms of the convergence rate and the steady-state error.
在这项研究中,我们提出了一种基于改进的最小平均峰度(LMK)算法的自适应傅立叶线性组合器(FLC),用于从期望信号中消除正弦噪声信号。在该框架中,采用改进的LMK算法代替传统的最小均方(LMS)算法来调整FLC的权系数。在FLC中使用所提出的LMK算法的根本原因是它提供了快速的收敛速率,较低的稳态误差和对正弦噪声分布的鲁棒性。通过与基于LMS算法的传统FLC算法进行比较,对所提FLC算法在消噪问题上的性能进行了评价。仿真结果表明,基于改进LMK算法的FLC在收敛速度和稳态误差方面都优于传统LMS算法。

Ali Yüce, N. Tan, Tufan Dogruer
The analysis of the open loop system in the design of the closed loop control systems is very important and useful in terms of being able to learn how the closed loop system will behave. In this paper, root locus graph of fractional order transfer function is plotted with the developed application using LabVIEW graphical programming language. A user panel has been designed using the LabVIEW graphical programming language. Interactive user panel is basic and user friendly for the computation and analysis. The root locus graph of the fractional order transfer function can interactively be plotted. Matsuda method is preferred for integer order approximation. With the interactive feature of developed application, the unit step response of closed loop control system can be plotted for a selected gain on the root locus graph panel.

Updating HD-Maps for Autonomous Transfer Vehicles in Smart Factories 智能工厂自动转运车辆高清地图的更新
Muhammed Oguz Tas, Hasan Serhan YAVUZ, A. Yazıcı
Autonomous robots are increasingly used in many fields to perform some special tasks. Autonomous transfer vehicles (ATV) in smart factories are one of the most critical components of industry 4.0. Mapping is the key process for the long term successful operation of ATVs. Although, robotic mapping is enough for the autonomous navigation of an ATV, high definition (HD) maps are required to perform the perfect behavior and ensure better interactions with the environment. HD maps can be created manually, but updating the maps is an open problem for sustainability of the performance. In this study, an HD-map update strategy is proposed for ATVs that operate in smart factories.
自主机器人在许多领域越来越多地用于执行一些特殊任务。智能工厂中的自动转运车(ATV)是工业4.0最关键的组成部分之一。测绘是全地形车长期成功运营的关键环节。虽然机器人地图对于ATV的自主导航来说已经足够了,但需要高清晰度(HD)地图来执行完美的行为,并确保与环境更好的交互。高清地图可以手动创建,但更新地图是性能可持续性的开放问题。本研究针对智慧工厂中营运的全地形车,提出一种高清地图更新策略。

Autonomous transfer vehicles (ATV) in smart factories are one of the most critical components of industry 4.0. Mapping is the key process for the long term successful operation of ATVs. Although, robotic mapping is enough for the autonomous navigation of an ATV, high definition (HD) maps are required to perform the perfect behavior and ensure better interactions with the environment. HD maps can be created manually, but updating the maps is an open problem for sustainability of the performance. In this study, an HD-map update strategy is proposed for ATVs that operate in smart factories.","PeriodicalId":357613,"journal":{"name":"2018 6th International Conference on Control Engineering & Information Technology (CEIT)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126126531","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}
