摘　　要：针对一阶线性时滞系统在工业控制中存在响应速度慢、静差问题,给出了一种模糊控制器设计。利用模糊集合的隶属度函数,模糊条件句和模糊控制规则,实现对一阶线性时滞系统的控制。利用Matlab提供的模糊系统工具箱对控制器进行了设计,并在Simulink环境下对系统进行了建模和仿真。仿真结果表明,模糊控制器提高了一阶线性时滞系统的动、静态特性,使系统获得了良好的控制性能,具有较好的应用价值。To the problem that the first-order linear delay system suffers slow response and offset, the design of a fuzzy controller is presented. Using membership function of fuzzy set, fuzzy condition sentence and fuzzy control rules, the fuzzy controller completes the control of the first-order linear delay system. The controller is designed with the fuzzy system toolbox provided by Matlab, and the system model and simulation are fulfilled based on Simulink environment. The simulation resuh shows that the fuzzy controller has improved dynamic and static property of the first-order linear delay system, and has obtained a better control quality.
