基于UEGO的柴油机EGR系统的鲁棒Smith预估器的仿真

Simulation of Robust Smith Predictor for Diesel EGR Based on UEGO

在各种可能的情况下,利用Matlab工具箱对鲁棒Smith预估控制器进行了仿真。仿真结果表明,Smith预估控制器对参数的变化具有很强的鲁棒性,闭环系统是稳定的,且控制器动态性能良好。

The Smith predictor is simulated by Matlab on various conditions. The results show that the Smith predictor is robust and steady and has better dynamic performance when parameters change.
