摘　　要：针对一类典型的非自衡过程控制对象 ,根据内模控制理论提出一种二自由度 PID调节器的设计方法。所设计的调节器仅有两个可调参数 ,而且被调参数与系统的性能直接相关 ,可使系统同时具有良好的目标值跟随特性和干扰抑制特性。仿真结果表明了它的有效性。The design procedure of the two-degree-of-freedom (2DOF) PID regulator for typical integrator and dead time process is proposed based on the internal model control(IMC) theory. The designed controller has only two adjustable parameters that are directly related to system performance. Good dynamic response performance of both command tracking and disturbance rejection characteristics can be achieved simultaneously. The simulation results are given to demonstrate the effectiveness of the controller.
