摘　　要：提出了一种实用的内模控制器的设计方法。为了使内模控制器能在工程中得以实现,通过在内模控制器前或后加入低通滤波器的方法,使得内模控制器可以通过模拟仪表来实现,也可以用数值计算的方法实现内模控制器,而且,低通滤波器的惯性时间常数,可以通过参数优化的方法获得。仿真结果表明,按上述方法设计的内模控制系统具有良好的各项品质指标。This paper presents a design method of practical internal model controller. In order to make the internal model controller can be realized in engineering, the low pass filter is joined before or after the inner model controller, so that the inner model controller can be realized by analog instruments, can also be calculated with the numerical method to realize the internal model controller, and the inertia time constant of the low pass filter can be obtained through parameter optimization method. Simulation results show that the internal control system designed by this method has good quality indicators.
