| 摘 要： | 针对三阶电液伺服系统,提出了一种新的PID控制器,把传统的PID控制器的阶次推广到分数领域,它不仅适用于分数阶系统,也适用于整数阶系统,并能取得一些优于整数阶PID控制器的效果.用滤波方法进行分数阶的微积分运算,直接求出传递函数,用Matlab/Simulink构造了PID模型,可直接在其它仿真系统中调用.仿真结果证明了该方法的正确性.

| Abstract: | For the three-order electro-hydraulic servo system,a new kind of PID controller,fractional order PID(Proportional,Integral and Derivative) controller,which is the generalization of classical integer order PID controller was proposed.It can be used for fractional order systems and some integer order systems,and may have some superior performances compared with the classical integer order PID controller.The computing method of fractional calculus was given,s-transform function was found directly and PID model was constructed with Matlab/Simulink,which can be used in other simulation system.The simulation outcomes verify effectiveness of the method proposed. |
