| 摘 要： | 磁悬浮平台控制系统是典型的非线性迟滞系统,难以获得精确数学模型,单纯采用经典PID控制或Fuzzy控制难以满足系统的快速性、稳定性、鲁棒性等要求。文章针对磁悬浮平台系统的特点,采用了Fuzzy控制和PID控制相结合的方法(P-Fuzzy-PI),应用比例控制提高系统输出的快速性,应用模糊控制改善系统的动态性能,应用积分控制可以消除静差,使系统稳态性能变好。仿真结果表明用P-Fuzzy-PI方法对悬浮平台进行控制,可以得到理想的控制效果。

| Abstract: | It's difficult to obtain precise mathematic model for magnetic suspension platform system with the nonlinear and hysteresis characters,so it's difficult to cater to the system requirement of rapidity,stability and robust by applying general PID or Fuzzy controller separately.Aimed at the characteristics of magnetic suspension platform system,a composite control model combining PID with Fuzzy(P-Fuzzy-PI) is introduced by applying P part to improve the system rapidity,applying Fuzzy part to improve the system dynamic characteristics and applying PI part which can erase inaccuracy to improve the system steady characteristics.The Fuzzy-PID controller has perfect effect on magnetic suspension platform system through simulation. |
