中文摘要
      针对现代工业过程中常用的网络PI控制系统, 分析了网络所诱导的时滞对PI控制系统性能的影响, 设计了一个模糊逻辑补偿器来实现对网络所诱导的时滞的补偿. 利用Hermite-Biehler引理在准多项式稳定性问题上的推广, 研究了具有模糊逻辑补偿的网络PI控制系统的稳定性问题, 给出了使闭环系统稳定的模糊逻辑调节参数的取值范围. 仿真结果验证了理论分析结果的有效性.
英文摘要
      For the networked PI control systems in many modern industrial processes, the effect of network-induced time delay on the performance of PI control systems is analyzed. A fuzzy logic modulator is designed to compensate the network-induced time delay. The problem of stabilizing networked PI control systems with fuzzy logic compensation is studied by applying the extension of the Hermite-Biehler theorem to the quasi-polynomial stability problem. The region of fuzzy logic modulator parameter value for the stability of the networked closed-loop system is provided. Simulation result shows the validity of the proposed work.
