本文提出了一种利用状态观测器的输出,通过高增益模型匹配,消除外扰影响的模型跟踪控制系统的设计方法.并将其引入带有时滞的控制系统,从而构成模型跟踪预测控制系统.计算机仿真结果表明:所提方法在输入加有阶跃外扰时,可以有效地消除外扰的影响. In this paper, a design method of model tracking control system based on output of state observer and matching of high-gain model to eliminate the influence of external disturbance is proposed and introduced into the control system with time delay to form model tracking control system. Computer simulation results show that the proposed method can effectively eliminate the influence of external disturbances when inputting stepped external disturbances.
