存在扰动的永磁同步电机混沌运动模糊自适应同步

摘要

电机的混沌运动并不总是有害的,在某种特殊应用场合中永磁同步电机的混沌运动是有益的,因此需要对永磁同步电机的混沌运动进行反控制.提出了一种存在扰动的永磁同步电机(PMSM)混沌运动的模糊自适应同步控制方法.分析了PMSM混沌运动的吸引子和lyapunov指数谱,使模糊控制规则满足系统的lyapunov稳定条件,设计模糊自适应控制器对存在扰动的PMSM混沌系统进行同步控制,仿真结果表明该方法可实现PMSM混沌运动的同步控制,具有较好的控制效果.%The chaotic motion of permanent magnet synchronous machine (PMSM) is good for some special industrial system, so the anti-control of the chaotic motion of PMSM is necessary. A fuzzy adaptive logic synchronization control method is proposed for the chaotic systems of PMSM with disturbance. Lyapunov exponents and attractors of chaotic motion are analyzed. Based on Lyapunov stability theory, fuzzy control laws are derived. The fuzzy adaptive controller is designed to achieve the synchronization control of the chaos system of PMSM with disturbance. Numerical simulations are presented to demonstrate the effectiveness of the proposed fuzzy adaptive synchronization schemes.
