基于模糊控制的Smith预估器的研究和设计

Research and design for the smith predictor based on fuzzy control

本文介绍了Smith预估控制原理,针对Smith预估器对象模型误差过于敏感的缺点,引入模糊控制代替Smith预估器中的PI控制,Matlab仿真结果表明采用模糊Smith预估控制一定程度上改进了常规PI Smith预估控制和模糊控制的缺点。

This article introduces the principle of the Smith predictor, however, Smith predictor is highly sensitive to the mismatching between the process model and the real process.So fuzzy Simth predictor is developed,in which fuzzy control is substituted for the PI control .The Matlab-based simulation acquires good results.
