| 摘 要： | 提出一种预测控制和遗传算法相结合的自整定ＰＩＤ控制算法．该算法利用预测技术克服时滞，利用遗传算法优化ＰＩＤ控制器的参数．通过对工业过程中典型的大时滞被控过程进行数字仿真表明，这种控制算法鲁棒性强、响应速度快、抗干扰能力强，对控制系统有扰动、参数时变尤其时滞时变的大时滞生产过程有较好的控制效果．

| Abstract: | An effective control algorithm, combined genetic algorithm with predictive control, is presented, which can overcome time delay with the predicting technique and optimize the parameters of PID controller using genetic algorithm. The simulation results show that the controller has enhanced response speed and robustness. It is suitable for the process with unknown time varying delay, disturbance and time varying parameters. |
