摘　　要：本文首先分析了当采样频率较高时，基于q算子的自校正零极点配置无静差跟踪控制器所面临的问题．在此基础上，给出一种基于δ算子的算法．给出了对比仿真结果．结果显示，在高速采样场合，基于δ算子的算法具有更好的跟踪性能．The problem of pole-zero placement controllers and self-tuning regulators with better set-point tracking is considered in the case of high-speed sampling rate. A new algorithm with δ-operator models is proposed.The δ-operator models have close connections with the original continuous-time versions. The new controller is compared with its digital counterpart, which is usually based on shift operator. Simulation results show the superiority of the δ-operator based algorithm over the one in the z-plane.
