摘　　要：通过仿真 ,比较CyboCon无模型单输入单输出控制器、基于鲁棒性能指标设计的PI控制器和基于经验整定方法设计的PI控制器在对象模型精确和模型变化情况下的控制性能 ,得出CyboCon无模型单输入单输出控制器与基于经验整定方法设计的PI控制器在性能上是相同的 。In this paper,the performances of CyboCon model free SISO controller,PI controller designed by robust specification,and PI controller designed by experiential formula are analyzed through simulation.The simulation is made in the situation where plant model is accurate and inaccurate.It is found that the performances of CyboCon model free SISO controller and PI controller designed by empirical formula are identical and some constrains have to be considered when PI controller is designed through robust specification.
