基于TrueTime的网络控制系统设计与仿真

摘要

This paper introduced the method of constructing the wired and wireless networked control system simulation platform by using TrueTime which is a simulation tool based on Matlab or Simulink. The model used both conventional PID and fuzzy PID considering the influence of time delay and dis-turbance. The simulation results show that fuzzy PID control is better than the conventional PID in the wired and wireless network control system. The paper also verified the fuzzy control can be widely used in the controller design for networked control systems and TrueTime toolbox can simulate network environment finely.%利用基于Matlab/Simulink的网络控制系统仿真工具TrueTime分别搭建了有线和无线网络控制系统仿真平台。模型考虑时延和干扰的影响，分别采用常规PID和模糊PID两种控制律。仿真结果表明：在有线和无线网络控制系统中，模糊PID均比常规PID控制效果更优，验证了模糊控制能广泛应用于网络控制系统的控制器设计，而TrueTime工具箱能较好地模拟网络环境。
