| 摘 要： | 提出了一种基于遗传算法整定的模糊PID控制器,并将其应用到光源伺服跟踪系统中.针对光源跟踪伺服系统,设计了模糊PID控制器,实现PID参数的在线调整.由于PID参数初值对于系统的控制效果影响较大,传统的齐格勒-尼科尔法初值整定效果不佳,因而利用遗传算法来整定模糊PID控制器的初值.仿真结果表明：基于遗传算法初值整定的模糊免疫PID控制器具有超调量小,响应速度快和鲁棒性强等优点,提高了系统的性能. |

| Abstract: | A fuzzy PID controller based on genetic tuning was proposed applied to the light source tracking servo-system.The fuzzy PID controller was designed to adjust parameters of the controller PID on-line for the light source tracking servo-system.And the initial parameter of PID had a potent effect on the control system,which was not well tuned for conventional Ziegler-Nichols algorithms,so the genetic algorithms was used to tune initial parameter for fuzzy PID controller.Simulation results showed that the fuzzy PID controller by genetic tuning had the advantage of smaller overshoot,quick response and stronger robustness,compared with the controller by Ziegler-Nichols’ tuning. |
