| 摘 要： | 为了提高整数阶PID控制器的控制精度,将控制器的阶次推广到分数阶领域,可得到分数阶PIλDμ控制器模型。借助一种数字实现形式,在时域中直接运用z变换方法,可计算分数阶PIλDμ控制器。对实例的仿真结果表明,分数阶PIλDμ控制器具有更佳的控制效果,分数阶次的合适选取对控制质量的改善明显。控制器对系统参数的变化不敏感,结构更灵活,鲁棒性也更强。

| Abstract: | To improve the accuracy of integer order PID controller,a fractional order controller with a digital implementation is proposed.In the time domain,the proposed controller can be computed with z-transform method directly.Simulation results show that,the fractional order controller is not sensitive to the changes of the system,and besides,it has good control effectiveness,flexible structure,and strong robustness. |
