| 摘 要： | 针对一类不稳定时滞过程，采用双环控制结构，首先使广义对象稳定，然后按内模控制原理设计了一种二自由度PID控制器．所设计的控制器具有两个可调参数，且被调参数与系统性能直接相关，可使系统同时具有良好的目标值跟踪特性和干扰抑制特性．仿真结果证明了它的有效性.

| Abstract: | A double loop structure is employed to a class of unstable process with time delay.After stabilizing the inner loop,the internal model control(IMC)principle is used to design a two-degree-of-freedom(2DOF)PID controller.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. |
