摘要
将传统的PID控制器或者传统复合型模糊控制器应用到主动电磁轴承系统中,其动、静态特性之间存在着一定的矛盾,较难达到理想的控制效果。将自适应模糊控制器和智能积分器相结合,提出了智能积分型自适应模糊控制器,以一个单自由度主动电磁轴承模型为例,比较了智能积分型自适应模糊控制器、传统模糊控制器和传统PID控制器的控制性能,并进行了仿真。仿真结果证明了智能积分型自适应模糊控制器的优越性。
When a traditional PID controller or a traditional composite fuzzy controller is applied to the active magnetic bearing system, it is difficult to achieve the good control performances because of some contradictions between its static and dynamic performances. Therefore, an adaptive fuzzy controller with intelligent integrator which was a combination of an adaptive fuzzy controller and an intelligent integrator in parallel was proposed. The performances of the PID controller, the traditional composite fuzzy controller and the adaptive fuzzy controller with intelligent integrator applying in the active magnetic bearing system were simulated and compared. The simulation results verify the advantages of the adaptive fuzzy controller with intelligent integrator.
