摘要
针对可控磁路式永磁悬浮系统多变量强耦合、非线性等特点,根据模糊PID控制器的设计思想,设计了一种基于鲁棒控制的模糊鲁棒控制器,可以在线调整控制器各参数。将该控制器与原鲁棒控制器进行仿真分析对比,结果表明该控制器可以使系统具有良好的鲁棒稳定性,实现系统对位移信号的跟踪和对外部扰动的抑制,适应被控对象的非线性和时变性,满足该悬浮系统的性能要求,与鲁棒控制器相比提高了系统的动态性能。
To solve the problems of multi-variable, strong coupling and nonlinear of permanent magnetic suspension system using variable flux path control method, basing on the design method of fuzzy PID controller, a fuzzy robust controller is designed which is used for adjusting the parameter of controller online. The results of comparing simulation between the fuzzy robust controller and traditional robust controller indicate that the form controller has excellent robustness. It can respond the input signal of displacement and realize the stability of system caused by disturbance, and can adapt the nonlinear and time-varying characteristics. The dynamic capability of controlled system is advanced.
