摘　　要：针对二自由度PID控制器参数整定困难的问题,提出了一种基于单亲遗传算法的二自由度参数整定方法。运用该算法分别对单自由度PID控制器和二自由度控制器进行了整定,并与传统方法整定的结果进行了比较。仿真表明,单亲遗传算法的参数整定方法,能有效地提高两类PID控制系统的性能,所设计的二自由度PID控制器可以使控制系统同时具有良好的目标跟随特性和干扰抑制特性。To solve the difficuhy in tuning parameters of Two Degree-of-Freedom （DOF） PID controller, a method of tuning parameters based on partheno-genetic algorithm is proposed. The parameters of both 1-DOF-PID controller and 2-DOF-PID controller are tuned using the proposed algorithm, and compared with the traditional tuning method. The simulation results show that the proposed approach can improve the two types of PID control system performance effectively. The 2-DOF PID controller designed by the pro- posed algorithm has the characteristics of command tracking and disturbance rejection.
