基于S函数实现的参数自整定模糊PID控制器

Parameter Self-tuning Fuzzy PID Controller Based on S Function

为使大时间延迟系统的控制性能得到改善,利用SIMULINK工具箱和S函数构造模糊控制系统的结构框图并进行仿真,通过编写S函数,将MATLAB和SIMULINK结合起来,实现参数自调整的复杂模糊控制系统的设计和高效仿真.将该控制器运用到隧道窑温度控制系统中,并取得了良好的控制效果.

In order to improve control performance for large time delay system,using SIMULINK toolbox and S function,a structure diagram of the fuzzy control system is constructed to simulate. Through the preparation of S function,combining with MATLAB and SIMULINK,the design and efficient simucation of the parameter self adjustment fuzzy control system is realized. Lastly,the controller is applied to the temperature control system of the tunnel kiln,and a good control effect has been achieved.
