Abstract

Networked control systems gain recently more attention because of the possibility of providing remote control of industrial processes (with the usage of, e.g., TCP/IP protocol) efficiently and cost-effectively. One of the problems that control engineers has to face while developing network control systems is the spiky nature of the network random delays, which can be better characterized by so-called α-stable processes which are described by fractional lower-order statistics (closely linked to fractional order calculus). This paper presents an implementation example of a networked control system for the temperature control of a Peltier module platform developed by Mechatronics, Automation, and Embedded Systems Laboratory (MESALab) of the University of California, Merced. The system provides a user the possibility to remotely run a PID control algorithm executed by JavaScript code in the user’s browser, performing the real-time control of the temperature of the Peltier module. Additionally the analysis of the system communication delays is performed. Obtained results show that the communication delays fits into a α-stable probability distribution with a heavy tail, indicating a fractional order behavior which effect can influence the control system performance.
具有分数阶延迟动力学的实验网络控制系统
网络控制系统最近获得了更多的关注,因为它可以高效和经济地提供对工业过程的远程控制(例如使用TCP/IP协议)。控制工程师在开发网络控制系统时必须面对的问题之一是网络随机延迟的尖尖性质,这种延迟可以用分数阶低阶统计量(与分数阶微积分密切相关)描述的所谓α-稳定过程来更好地表征。本文介绍了由美国加州大学默塞德分校机电、自动化和嵌入式系统实验室(MESALab)开发的Peltier模块平台温度控制网络控制系统的实现实例。该系统为用户提供了在用户浏览器中远程运行由JavaScript代码执行的PID控制算法的可能性,实现了对Peltier模块温度的实时控制。此外,还对系统的通信延迟进行了分析。结果表明,通信延迟符合α-稳定的概率分布,具有重尾,表现为分数阶行为,其效应会影响控制系统的性能。
