| 摘 要： | 某高空作业平台自动调平系统存在调整时间长、响应速度慢的问题。为改善一般位置随动系统的性能,针对该系统的大阻尼特征,设计了常规PID控制算法。通过仿真实验,获得一组较优控制参数,使得系统响应快速性得到改善,但也存在超调过大的缺陷。为进一步优化系统,将模糊控制与PID控制结合,设计了一种模糊PID控制器。仿真分析结果表明:应用该模糊PID控制器,系统的调整时间与超调量都得到了明显优化。

| Abstract: | The automatic leveling system of an aerial working platform has the problems of long adjustment time and slow response speed.In order to improve the performance of general position follow up system, a conventional PID control algorithm was designed according to the large damping characteristics of the system. A set of better control parameters was obtained through simulation experiment.The response speed ability of the system was improved by taking advantage of these parameters, but the system also had defects of excessive overshoot.In order to further optimize the system, a fuzzy PID controller was designed by combined fuzzy control with PID control. The simulation results show that the adjustment time and overshoot of the system are obviously optimized using this fuzzy PID controller |
