摘要: 基于网络控制仿真软件TrueTime以及Matlab/Simulink环境构建了一个无线网络控制系统仿真模型,对系统模型和控制策略进行了仿真实验;设计了一种Fuzzy-PD控制器,提出了一种无线网络控制器参数离线优化的方法,即利用ITAE作为重要参考指标对Fuzzy-PD控制器进行离线调整,通过调整Fuzzy-PD控制器的转换参数改善控制器在不同网络带宽占用率下的控制性能。仿真结果验证了Fuzzy-PD控制算法优于传统的PD控制算法和Fuzzy控制算法。

Abstract: A simulation model of wireless networked control system was established on the basis of TrueTime and Matlab/Simulink,and some simulation experiments were performed based on the system model and control strategies.A Fuzzy-PD controller was designed,and a method of parameter optimization off-line was proposed by using ITAE as an important reference index.The control performance was improved by adjusting the converted parameter of the Fuzzy-PD controller based on different network bandwidth occupied rates.The advantage of the Fuzzy-PD control algorithm was validated as compared with PD and Fuzzy control algorithm by the simulation results.
