一类切换模糊PID控制器设计及其仿真

提出了一类高动态性能切换模糊PID控制器设计方法.通过对传统PID控制中比例控制和微分控制作用的分析,结合模糊PID控制器鲁棒性能和自适应性好的优点,设计了一类新的模糊控制器.由于该类控制器先后经历比例控制,微分控制和模糊PID控制的切换,使被控系统不仅具有一般模糊PID控制器的所具有的良好的鲁棒性能和自适应性,而且与一般模糊控制器相比具有更小的超调量和调节时间,是一类动态性能良好的控制器.最后将该控制器应用于一伺服系统进行仿真对比,并给出了Simulink仿真框图.仿真结果说明了该控制器的优越性.

Design and simulation of a class of switch fuzzy PID controller

A new method a class of switch fuzzy PID controller with high dynamic performance is proposed. By analyzing to the function of proportion control and differential control of traditional PID, join with the advantage of robustness and adaptability of fuzzy PID controller, a new fuzzy controller is designed. As the con troller experience successively proportion control, differential control and fuzzy PID control, the controlled system not only have well robust performance as usual fuzzy PID controller, also have ,tore small overshoot and adjusting time, is a controller with well dynamic performance. At last the controller is used in a servo system for contrast simulation, and the simulation frame of Simulink is gave. The result testifies the superiority of the controller.
