频谱分析在控制器参数自调整中的应用

Application of Spectrum Analysis in Self－tuning Parameter of the Controller

介绍了一种简单的自适应控制器的设计方法。为了判断系统的控制状态，可以对系统在单位阶跃信号作用下的瞬态响应作频谱分析，并以此为依据来调整控制器的PID参数，使控制系统始终处于最佳状态。

A method to design a kind of simple adaptive controller is introduced. To know the control state of the system, the spectrum analysis of the transient response of the system to unit step input canbe down,and it can be a criterion to tune the PID paramther of the controller, so that the control system is always in optimum state.
