Optimization of the THD and the RMS voltage of a cascaded multilevel power converter 级联多电平变换器的THD和均方根电压优化
L. P. Fernandez, Jorge Luis Diaz Rodriguez, Edison Andres Caicedo Peñaranda
This paper deals with the optimization of common source cascaded multilevel inverter with 17 steps per line, using a multiobjective genetic algorithm that allows generate an optimized PWM modulation waveform. The aim is to minimize the total harmonic distortion (THD) to a value close to zero, but keeping the root mean squared (RMS) voltage at the desired value, while the magnitude and the frequency of the output voltage waveform change progressively. To evaluate the performance of the algorithm, a simulation was carried using an asymmetry converter with two H-bridge stages and a 1:3 transformation ratio. The results allow verifying the THD optimization in the first 50 harmonics and to obtain the RMS voltage value the same as the rated value.

PD–Fuzzy+I control for a two degrees-of-freedom parallel robot 二自由度并联机器人的PD-Fuzzy +I控制
Boris L. Martínez-Jiménez, Orlando Urquijo, Andrés Feitó, Dianelis Garcia, E. Rubio
Driving simulators are used for the training of vehicle drivers and they have varied applications in games and entertainment. These platforms minimize the use of real vehicles, with the consequent saving of resources. Here, control strategies for nonlinear systems applied in parallel robots using electropneumatic actuators are developed. These actuators are cheaper but, at the same time, more difficult to control due to the compressibility of air, friction and uncertainties. In this paper, a nonlinear PD-fuzzy + I control strategy is used to deal with highly non-linear elements and uncertainties. Also, control algorithm soften the controls and thus protect the valves and pneumatic pistons. Simulation results are provided to show the effectiveness and the potentialities of the proposed control strategy.

Identification and Process Control for MISO systems, with Artificial Neural Networks and PID Controller 基于人工神经网络和PID控制器的MISO系统辨识与过程控制
Eduardo Viera, Héctor Kaschel
Industrial processes with multiple input and single manipulated variables are very complex systems to control in automatic models. Such is the case with processes related to gases extraction or transport phenomena. The present research is focused on the development of a control algorithm (automatic control strategy), based on artificial neural networks, to identify an industrial process by using process historical records, as well as knowledge from the operation itself. The output of the identification stage feeds a classic PID controller to perform control actions (hybrid controller). Here, an actuator or final control element is modeled, estimating its space-state dynamic equation. With the estimated model, a local control loop is conformed controlling the main process or manipulated variable. For this, the process of gases transport in a copper smelter plant was chosen, where the necessary data and scenarios for the proposed control algorithm testing was obtained. This application attempts to present a solution to problems inherent to manual control, multiple key variables coexisting in a system, mechanical stress in equipment due to manual actions, etc. The control strategy is based on a computer simulation made with real process data, showing improvement of the transient periods in the final actuators due to control signals, as well as establishing that these kinds of technologies could be implemented in both, an existing plant hardware/software or in a conventional control system.
具有多输入和单被控变量的工业过程在自动化模型中是非常复杂的系统。与气体抽取或输送现象有关的过程就是这种情况。目前的研究重点是开发一种基于人工神经网络的控制算法(自动控制策略),通过使用过程历史记录以及操作本身的知识来识别工业过程。辨识阶段的输出馈入经典PID控制器执行控制动作(混合控制器)。在这里,对致动器或最终控制元件进行建模,估计其空间状态动力学方程。利用估计的模型,形成一个局部控制回路,控制主要过程或被控变量。为此,选择了某铜冶炼厂的气体输送过程,获得了所提出的控制算法测试所需的数据和场景。该应用程序试图解决手动控制固有的问题,系统中存在多个关键变量,由于手动操作导致设备的机械应力等。该控制策略基于使用真实过程数据进行的计算机模拟,显示了由于控制信号而改善了最终执行器的瞬态周期,并确定了这些类型的技术可以在现有工厂硬件/软件或传统控制系统中实现。

Alternative Method for the Fermentation of Cocoa Beans 可可豆发酵的替代方法
Pablo Parra, O. Castillo, P. Maldonado
This article shows the results of the tests carried out with cocoa beans in order to reduce the fermentation time. We have proceeded to experiment with a pre-fermentation stage, which consists of inoculating the cocoa bean with bacteria of the lactobacilli type. This pre-fermentation stage lasts 24 hours under an anaerobic environment. Subsequently, the cocoa bean is introduced into a fermenting system, whose technology has been developed for this research. This system consists of a static chamber of controlled temperature in an aerobic environment, inside which a rotating stainless steel basket is placed, where the grain to be fermented is housed. The cocoa will remain for another 24 hours in this chamber. It has managed to ferment the cocoa in a time of 48 hours, that is, it has managed to reduce the time compared to traditional or craft processes, whose duration ranges from 4 to 7 days.

Implementation and comparative analysis of fractional order PID Embedded Controllers, applied to speed control of a robotic prosthesis 分数阶PID嵌入式控制器的实现与比较分析,应用于机器人假肢的速度控制
C. A. Calderon, Roger Sarango, Edwin Macas, Cristian Ramírez, F. Rivas-Echeverría, W. Hernandez
This paper is part of the “Hand of Hope” research project, which seeks to develop low-cost robotic prostheses for people with motor disabilities in their upper limbs. The objective of this research is to design and implement a fractional order PID embedded controller (FOPID), applied to the speed regulation of the elbow joint based on DC motor, in a robotic prosthesis. The set of parameters for the tuning of a FOPID controller are five: proportional constant, integration constant, derivative constant, and non-integer orders of the integral and derivative terms $(K_{P}, K_{I}, K_{D}, lambda, mu)$. In order to fulfill the objective, three phases were executed: first, the several methodologies involved in the design and implementation of FOPID controllers were applied in an autonomous embedded system; then, they were implemented and applied to a mechatronic system; finally, the performance of the fractional controllers was analyzed and compared, the comparison of the controllers was performed based on the time parameters (settling time, overshoot), and the performance indexes (IAE, ITAE, ISE, and ITSE). As results of the present work: 14 types of fractional controllers were designed, of which 9 were implemented in an embedded system based on the multicore FPGA/Processor architecture, and the programming of the mathematical control functions were developed in LabVIEW FPGA and RT; after the experimental evaluation, the embedded controller with higher performance was the FOPID Ziegler-Nichols $/Nelder$-Mead/ISE, the results obtained were Ts $= 0.22s$ and PO$=7.1text{S}$%.
这篇论文是“希望之手”研究项目的一部分,该项目旨在为上肢运动障碍的人开发低成本的机器人假肢。本研究的目的是设计并实现一种分数阶PID嵌入式控制器(FOPID),应用于基于直流电机的机器人假体肘关节的速度调节。FOPID控制器的整定参数集有五个:比例常数、积分常数、导数常数和积分项和导数项的非整数阶$(K_{P}, K_{I}, K_{D}, lambda, mu)$。为了实现这一目标,分三个阶段进行:首先,将FOPID控制器设计和实现中涉及的几种方法应用于自主嵌入式系统;然后,将其实现并应用于机电一体化系统;最后,对分数控制器的性能进行了分析和比较,基于时间参数(沉降时间、超调量)和性能指标(IAE、ITAE、ISE、ITSE)对控制器进行了比较。研究结果表明:设计了14种分数控制器,其中9种在基于多核FPGA/Processor架构的嵌入式系统中实现,并在LabVIEW FPGA和RT中开发了数学控制函数的编程;经过实验评估,性能较高的嵌入式控制器为FOPID Ziegler-Nichols $/Nelder$ -Mead/ISE,得到的结果为Ts $= 0.22s$和PO$=7.1text{S}$%.

In order to fulfill the objective, three phases were executed: first, the several methodologies involved in the design and implementation of FOPID controllers were applied in an autonomous embedded system; then, they were implemented and applied to a mechatronic system; finally, the performance of the fractional controllers was analyzed and compared, the comparison of the controllers was performed based on the time parameters (settling time, overshoot), and the performance indexes (IAE, ITAE, ISE, and ITSE). As results of the present work: 14 types of fractional controllers were designed, of which 9 were implemented in an embedded system based on the multicore FPGA/Processor architecture, and the programming of the mathematical control functions were developed in LabVIEW FPGA and RT; after the experimental evaluation, the embedded controller with higher performance was the FOPID Ziegler-Nichols $/Nelder$-Mead/ISE, the results obtained were Ts $= 0.22s$ and PO$=7.1text{S}$%.","PeriodicalId":176587,"journal":{"name":"2018 IEEE International Conference on Automation/XXIII Congress of the Chilean Association of Automatic Control (ICA-ACCA)","volume":"33 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":"124480299","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}
