根据一个控制系统的脉冲响应，文中提出了一种由计算机辅助的数字ＰＩＤ控制器的设计方法。所设计的控制器可以近似地实现任意给定的闭环响应，控制器参数由最小二乘法确定，该方法的意义在于建立了一个时域指标与调节器参数之间的关系，该方法只需稍加修改便可以用来设计其它类型的控制器。
According to the impulse response of a control system, a design method of computer-aided digital PID controller is proposed in this paper. The proposed controller can approximate any given closed-loop response, and the controller parameters are determined by the least square method. The significance of this method lies in the establishment of a relationship between the time-domain index and the regulator parameters. Modifications can be used to design other types of controllers.
