该文介绍了基于幅值裕量与相位裕量参数整定方法的分数阶PIλDμ控制器的设计方法,并给出了分数阶控制器的多种数字实现方法。仿真实例结果表明分数阶控制器比整数阶控制器具有优良的控制品质及其对系统参数变化的鲁棒性。
In this paper, the design method of fractional order PIλDμ controller based on amplitude margin and phase margin parameter tuning methods is introduced, and several digital realization methods of fractional order controller are given. Simulation results show that Fractional order controllers have better control quality and robustness to system parameters than integer order controllers.
