大时延系统的新型Smith预估控制器

A New Type Smith Predictor Control for Large Time-delay System

本文在Smith预估法及其改进型的基础上,给出了一种新的Smith改进型。这种方法通过解除Watanabe法中对控制器的一个约束条件,使具有纯时延系统的控制器设计更为合理,有效地克服了现有方法中存在的问题。仿真例子表明,该方法较好地解决了大时延系统的控制问题。

This paper suggests a new modified Smith's predictor-control. The key point is to relax a constraint condition of the controller proposed by K. Watanabe. This method is particularly suitable for designing system with large time delay. The dynamic performance of the resulting system is better than that of previous methods. Some digital simulation and digit-analogous simulation results are given.
