时滞系统的二自由度控制
TWO-DEGREE-OF-FREEDOM CONTROL FOR TIME-DELAY SYSTEM
-
摘要: 针对时滞系统，提出了一种二自由度控制方法．这种方法将Smith预估控制和内模控制有机结合，把系统的目标值跟踪特性和干扰抑制特性分离，可以使系统同时获得良好的目标值跟踪特性、干扰抑制特性和鲁棒性．理论分析和仿真结果表明这种方法的有效性．Abstract: A two degree of freedom (2DOF) control method for time delay system is proposed.It combines Smith predictor with internal model control (IMC) and decouples the setpoint tracking response from disturbance rejection response.The proposed method gives very good dynamic response performance and robustness simultaneously.Theoretical analysis and simulation results show that the proposed control method.
