| 摘 要： | 讨论了对非最小相位过程，设计一种抑制可测周期扰动和跟踪周期设定值的新型前馈控制器。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。在过程存在不确定性时，在周期信号作用的频率域内根据过程的频率响应，设计了有效的控制器。

| Abstract: | A novel feedforward controller is derived for rejection of measurable periodic disturbances and tracking of periodic setpoints, when the process in non-minimum phase. The resulting controller is a finite impulse response (FIR) filter and hence pro blem of non-minimum phase zero cancellation is avoided. In the presence of process model uncertainties, the efficient controller can be designed by using the frequency response of the process at the frequences defined by the periodic signals. |
