| 摘 要： | 本文分析了常规PID控制器,模糊自适应PID控制器和变结构模糊PID控制器的原理,并设计了3种控制器。针对同一控制对象进行了ATLAB仿真,分别对比了被控对象参数和结构均不变、被控对象参数改变、被控对象结构改变等3种不同情况下控制器的鲁棒性。从仿真结果可以看出,变结构模糊PID控制器在3种情况下的鲁棒性最好。

| Abstract: | This paper analyzes the principles of conventional PID controller, fuzzy adaptive PID controller and variable structure fuzzy PID controller, then designed the three controllers. Conducted the MATLAB simulation for the same control object, then compared the robustness of the controller for three different situations in parameters and structure unchanged, parameter changes, structure changes, We can see from the simulation results that the robustness of variable structure fuzzy PID controller is best in three cases. |
