摘　　要：针对工业过程控制对象,将内模控制与二自由度PID控制有机结合,提出一种鲁棒二自由度PID控制方法,可以有效抑制参数变化对系统的影响,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了这一方法的有效性。Based on the internal model control (IMC) theory and two-degree-of-freedom (2DOF) PID control structure,a robust 2DOF PID control scheme is proposed for the industrial process plant. Very good dynamic response performance of both the command tracking and disturbance rejection characteristics and robustness can be achieved simultaneously. Theoretical analysis and simulated results are given to demonstrate the effectiveness of the proposed control scheme.
