The resulting controller is a finite impulse response (FIR) filter and hence problem of non-minimum phasezero cancellation is avoided.
这种控制器给出了避免非最小相位过程零极点对消的有限脉冲响应滤波器。

A repetitive controller can be obtained by designing a zerophase shift low pass filter. With the help of digital signal processing and software tools, it is easy to design a satisfactory controller.
