摘　　要：针对压力机位置伺服控制系统的大惯量、强非线性等问题,提出一种基于分数阶微积分的分数阶PIλDμ控制策略,给出了分数阶控制器的数字实现方式。分数阶控制器的分数阶微积分可以增加传统PID控制器的设计灵活性和系统的稳定性。为验证分数阶控制器的控制效果,在Matlab/Simulink下建立了压力机位置伺服系统模型。仿真结果表明:分数阶控制器的控制效果优于传统的整数阶控制器。In order to solve the problems existed in servo press control system, a new fractional order PID control strategy based on fractional calculus was presented for the slide position control system. For actually implementation, an approximation method to realize the designed fractional order PID controller was introduced. The fractional order calculus of the fractional order controller proposed can improve the design flexibility and the system stability. The simulation results indicate that the fractional order PID controller, if properly designed and implemented, will work better than the traditional integer order PID controller.
