摘　　要：针对塑焊机温度控制,提出了一种基于遗传算法寻优的PID控制方法。该控制器以系统误差控制输出上升时间和超调量构成的函数为性能指标,利用遗传算法全局搜索能力获取一组最优的PID参数Kp,Ti,Td,并且能根据实时获取的误差在线调整参数。应用结果表明,该温度控制器具有良好的动静态特性和鲁棒性。Aiming at the temperature control for the plastic welder, a kind of GA-based PID control method is presented. The performance index of the controller is a function that consists of error, output, rising time and overshooting of the system. A group of optimum PID parameters Kp, Kd and Ki, are acquired with the aid of global search ability of GA and PID parameters can be adjusted on-line based on real time error. Application results show that the temperature control system has good dynamic and static performances as well as robustness.
