摘要
为保证大时滞复杂系统的稳定性和抗干扰性,结合模糊控制和常规PID控制的优点,设计了一种参数自整定模糊PID控制器,根据其输出形式的不同,采用了位置式和增量式2种方法对时滞系统进行了有效控制,利用Matlab软件的Simulink和Fuzzy工具箱进行了仿真.结果表明:增量式输出方法时控制效果更好,并具有零超调、无静差、过渡时间短、稳定性好等特点.根据实验结果,总结出了调整模糊PID控制器各参数的一般规律和设计方法.
A parameter self-tuning fuzzy PID controller combined with fuzzy control with conventional PID control is designed to guarantee the interference suppression and stability of the Complex Large Scale Time Delay System. And according to its different output form, two methods, the position type and incremental type, are developed to control a time lag system effectively. Then the Simulink and Fuzzy tool boxes of Matlab are used to conduct computer simulation. The results show that the incremental type is better with zero overshoot, no static error, shorter transient time and superior stability. Finally the general rules for adjusting the parameters and the main methods of designing the fuzzy PID controller are obtained.
