计算机辅助带时延多变量系统的离散控制设计

本文将Smith预估技术与逆 Nyquist 阵列法结合对多时延多变量对象进行离散控制系统设计,采用这种方法设计出的控制器易用计算机实现,系统仿真结果也是令人满意的。

A computer aided design method which combines the Smith's prediction techni-que and the inverse Nyquist array method is presented.The method can be usedfor designing discrete control systems of multivariable processes with multiple timedelay elements.The derived controller structure is easy to be implemented onmicrocomputer.The simulation results are presented also.
