S域(s-domain)和Z域(z-domain)是信号处理中常用的两种不同的数学表示方法。 S域是用连续时间(analog)表示信号和系统的域。在S域中,信号和系统的输入和输出是连续时间函数,可以用连续时间的微分方程或传递函数来描述。S域适用于对连续时间系统进行建模和分析。 Z域则是用离散时间(discrete)表示信号和系统的域。

一般使用的增量式PID属于后向差分法,即将S domain中的左半平面映射到Z domain的以(0.5,0)为圆心,0.5为半径的圆中。 频率无混叠,但是失真较大,尤其是在Ts(采样频率)较低时。 ①s平面与z平面映射关系 s左半平面(s£0)映射到z平面为圆心(1/2,0),半径1/2的小圆内部。映射一一对应,频率无混叠 ②若D(s...
