本文应用模糊控制技术,设计了一种二输入三输出模糊自整定PID控制器,对锅炉汽包水位进行控制,实现了PID参数的自适应调节。利用MATLAB对控制系统进行仿真。结果表明,该控制器自整定能力及鲁棒性比传统PID控制器更强,响应速度快、精度高,同时对虚假水位有较好的控制效果。matlab实践研究。-In this paper, fuzzy control technology, the design of a two input and three output fuzzy self-tuning PID controller of the boiler drum water level control, the realization of the adaptive PID parameters. Using MATLAB simulation of control systems. Results show that the controller self-tuning capability and robustness stronger than the traditional PID controller, fast response, high accuracy and false at the same time the water level has good control effect. Practice matlab.
