摘　　要：　内模控制结构中的一阶反馈滤波自提出以来,以其设计简单,调节参数少而得到广泛应用,但在实际问题中一个调节参数往往难于协调快速性和平稳性,针对这一情况本文提出用有两个调节参数的二阶反馈滤波模型进行改进,并通过仿真检验表明,这种方法可以获得比简单的一阶反馈滤波更好的系统性能。Since the first order feedback filter in IMC was proposed, it has been widely used because of its easily designed method and simple tuning policy. In practice, this filter has difficulty in adjusting the speed and stability. To this problem, we propose an improved Solution based on the second order feedback filter with two adjusting parameters which exhibits better performance than the first one.
