In this paper, a step-up dc-dc converter for mobile device applications is proposed. The converter is operated with 1 MHz high switching frequency. The power stage of converter includes an inductor, an output capacitor, MOS transistors and feedback resistors for control loop. The control stage consists of an error amplifier, comparator, a ramp generator for PWM block, bandgap reference and soft start block with power transistor. Also, the circuit includes protection block such as over voltage protection (OVP), under voltage lock out (UVLO) and thermal shutdown (TSD) block. The proposed step-up converter has been designed with a 0.18 um CMOS process technology. Simulation results show an output voltage of 5 V with a ripple of 40 mV at the output current of 100 mA for an input voltage of 3.3 V.

The paper proposes an approach to design optimal receding horizon controller for tracking control a TRMS (twin rotor multiple input multiple output system), which is a nonlinear system with two degrees of freedom, cross couplings and perturbed additionally by system disturbances. On the contrary to all other MPC controllers, which use consistently a finite horizon and discrete time model of controlled object, the here proposed controller uses an infinite horizon and continuous time nonlinear model. Hence it always guarantees the adaptive tracking stability of obtained closed loop systems in real time, without using an additional penalty function in objective function as usual. The obtained simulation results by using this controller have confirmed its promising applicability in practice.
针对双转子多输入多输出系统(TRMS)这一具有交叉耦合和附加扰动的两自由度非线性系统,提出了一种最优后退水平控制器的设计方法。与所有其他MPC控制器一贯使用被控对象的有限水平和离散时间模型相反,本文提出的控制器使用无限水平和连续时间非线性模型。因此,该方法能够实时地保证所得到的闭环系统的自适应跟踪稳定性,而无需像通常那样在目标函数中加入额外的惩罚函数。利用该控制器得到的仿真结果证实了其在实际应用中的良好适用性。

This work develops a technique to design a feedback stabilizing control law for an unstable autonomous switched system. This method is analyzed and then applied to the DCDC buck converter when considering the uncertainty of the parameters in the model. Based on this model, a control law is design to allow the output voltage track a reference voltage when the load is changed. The control objective is to find the switching strategy where the state of the system converges to the equilibrium in the presence of the uncertainty of the system. The design problem is cast into an optimization problem which can be solved via the LMI toolbox in Matlab. The tracking error is bounded in a certain region. The simulation results using Simulink in Matlab are presented to validate the capability of the control system.

This paper presents the design of a compliant bio-inspired camera-positioning mechanism. The device combines human muscle actuation scheme and spherical mechanism with the aim of miniaturizing the orienting mechanism. The active orientation system which controls two DOFs (pan and tilt) were synthesized by using compliant mechanism. The flexible mechanisms utilize the deflection of curved beams to drive the orienting modules. A shape and size optimization process using genetic algorithm was used for the design. The multi-objective of the optimization problem is the maximum orienting angles and a linear input-output relation. To demonstrate the feasibility of the optimum design, finite element analysis was carried out. The results show that the proposed design exhibits essential characteristics of a camera-orientation system such as light weight, compactness and high precision.

Pub Date : 2017-07-01 DOI: 10.1109/ICSSE.2017.8030872

Recently, RGB-D cameras have been widely used to perform 6-D pose estimation of target objects for robotic manipulation. Such applications require accuracy shape measurements for 3-D modeling of the objects. In this work, we develop an RGB-D camera based on the structured light (SL) techniques with gray-code encoding and decoding. The intrinsic and extrinsic parameters of the camera system are determined by a calibration process. 3-D reconstruction of the object surface is based on a ray triangulation principle by computing the intersection point. In the implementation, we construct an RGB-D sensing system with an industrial camera and a digital light projector. In the experiments, real world objects are used to test the feasibility of the proposed method. The evaluation carried out using planar objects has demonstrated the accuracy of our RGB-D camera system.

This paper presents an approach to diagnose batteries with the help of microcontroller and smartphone. It aims to determine the available capacity, the state of charge (SoC) and the state of health (SoH) of a battery. A battery is aged by charging and discharging cycles, this process degrades the chemical composition of the battery. Thus, this paper aims at using two-pulse test to determine Ampere hour capacity (AHC), SoC and SoH of a valve regulated lead acid (VRLA). These parameters are related to the voltage drop after each pulse of current discharge. By using a microcontroller and smartphone, it is possible to easily change the controller parameters according to different size of battery. The microcontroller will be used to control current discharge based on two-pulse method and a discrete PID. A smartphone with an application based on Android program and via Bluetooth communication allows to change the parameters for the controller and monitor the performance of battery test. This concept is validated by simulations and experiments on an emulated system for availability reasons. This work takes place in a larger process which aims at providing local solutions for local problems according to the “Jugaad” philosophy, which can be seen as “frugal innovation”. The main idea is to re-use “old” elements such as automotive batteries in this case, to propose cheap and local solutions for off-grid village electrification.
本文提出了一种利用单片机和智能手机对电池进行故障诊断的方法。它旨在确定电池的可用容量、充电状态(SoC)和健康状态(SoH)。电池会随着充放电循环而老化,这个过程会降低电池的化学成分。因此,本文旨在利用双脉冲测试来确定阀控铅酸(VRLA)的安培小时容量(AHC)、SoC和SoH。这些参数与每次脉冲放电后的压降有关。通过使用微控制器和智能手机,可以根据不同尺寸的电池轻松更改控制器参数。单片机将采用双脉冲法和离散PID控制电流放电。在智能手机上安装基于Android程序的应用程序,通过蓝牙通信,可以改变控制器的参数并监控电池测试的性能。由于可用性的原因,该概念通过仿真和实验在仿真系统上得到验证。这项工作发生在一个更大的过程中,旨在根据“Jugaad”哲学为当地问题提供当地解决方案,这可以被视为“节俭创新”。主要的想法是重新利用“旧”元素,如汽车电池,为离网村庄的电气化提供廉价和本地化的解决方案。

Systems are becoming more complex due to uncertainties arising from rapid global technological progress and the growing involvement and interconnectedness of the human factor. Thus new management approaches are needed in order to improve system management effectiveness and efficiency. This research addresses critical issues in management decision-making processes for complex systems, and proposes a System of Systems (SoS) management framework to assist system engineers to assess continuously a complex situation and develop systemic solutions to problems. This paper demonstrates the usefulness of an SOS management framework using modelling and simulation. A case study examines the application of the new approach in the emergency recovery management of the Fukushima Daiichi Nuclear Power Plant disaster in Japan. Based on research related to this incident and the recovery efforts following, the paper shows that the SoS approach can have benefits for complex system management, providing flexibility while at the same time retaining the ability to regulate the degree of control of the system.

Ultrasonic welding of carbon paper and proton exchange membrane (PEM) for membrane exchange assemblies (MEAs) of fuel cells (FCs) is a viable technology to replace hot-pressing, which may be time consuming and energy inefficient. Ultrasonic spot welding of carbon paper and PEM is investigated in order to understand the bonding mechanisms and obtain the suitable processing parameters. Micrographs of the tested specimens are examined to evaluate the welding quality. Effects of the welding time on the quality of the ultrasonic welds of the MEAs are studied.

It is found that joints made by ultrasonic welding has the strength comparable to that of the base material. Values of welding time, holding time and downward force for successful bonding in terms of mechanical strength are obtained.","PeriodicalId":296191,"journal":{"name":"2017 International Conference on System Science and Engineering (ICSSE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129519100","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}

In this study, we present control system based on cerebellar model articulation controller (CMAC) for nonlinear systems to achieve high precision trajectory tracking. The proposed control system includes the CMAC with its fast learning and good generalization capability is applied to approximate uncertainties or model parameter variation to attain error function minimum and a compensator controller (CC) is designed to cancel the approximation error for guaranteeing the stable of the system. The gradient descent method is used to turn online parameters of the CMAC and the stability of the control system can be guaranteed by the compensator controller. The experimental results of Tank Pressure Control and Tank Water Level Control Systems prove that the robustness and effectiveness of the proposed controller.
在本研究中,我们提出了一种基于小脑模型关节控制器(CMAC)的非线性系统控制系统,以实现高精度的轨迹跟踪。该控制系统将具有快速学习和良好泛化能力的CMAC应用于逼近不确定性或模型参数变化,使误差函数最小,并设计补偿控制器(CC)来抵消逼近误差,保证系统的稳定性。采用梯度下降法对CMAC的参数进行在线翻转,补偿控制器可以保证控制系统的稳定性。水箱压力控制和水箱水位控制系统的实验结果证明了该控制器的鲁棒性和有效性。
