Finite-Time Chaotic Synchronization Control of Permanent Magnet Synchronous Motor

阐述了一种永磁同步电机有限时间混沌同步控制的方法。建立永磁同步电机无量纲模型并对系统混沌行为进行分析,基于Lyapunov稳定性理论与主动控制原理,设计了系统的有限时间状态反馈控制器,通过驱动-响应同步法实现了永磁同步电机的有限时间混沌同步。仿真验证了该方法具有较快的响应能力。

A control method of finite-time chaotic synchronization of PMSM was presented.The dimensionless models of permanent magnet synchronous motor and brushless DC motor were given and the chaotic behavior of each system was analyzed.The finite-time state feedback controller for the system was designed based on Lyapunov stability theory and active control principle.The finite-time chaotic synchronization of permanent magnet synchronous motor was realized by the drive-response synchronization method. Simulation results show that the presented method has faster response ability.
