摘要
永磁同步电动机是一个多变量、非线性、强耦合对象。在综合比较自适应控制、模糊控制、滑模变结构控制的优点的基础上,提出了一种自适应模糊滑模PI控制策略。滑模变结构控制具有强大的对系统参数变化和外部扰动良好的鲁棒性的能力,自适应模糊PI控制逼近非连续控制,削弱抖振,同时保证系统渐进稳定。仿真结果验证了所提出的控制策略的有效性。
An adaptive fuzzy PI-sliding mode control(AFPISMC) Strategy is proposed for permanent magnet synchronous motor(PMSM) which is a multivariable,nonlinear,forceful coupled object,which combines the merits of sliding-mode control(SMC),the fuzzy inference mechanism and the adaptive algorithm.SMC has good robustness with regard to parameter variation and external disturbance.Adaptive fuzzy PI mechanism is used to approximate the discontinuous control,to attenuate chattering effectively.The analysis of simulations reveals the effectiveness of the proposed method.
