非均匀气隙永磁同步电机的有限时间自适应混沌同步

摘要

A novel finite-time adaptive synchronization controller is proposed for the permanent magnet synchronous motor (PMSM) with non-smooth air-gap. In the proposed control strategy, the active control is used to decouple the linear terms and nonlinear terms of the dynamic error system. Then, based on the finite-time stability theory and adaptive control approach, the designed novel controller could realize chaos synchronization of the drive-response system in finite time. Finally, numerical simulations are provided to demonstrate the effectiveness and usefulness of the proposed finite-time adaptive control strategy.%以非均匀气隙永磁同步电机（PMSM）混沌系统为对象，提出一种有限时间自适应混沌同步控制方法。利用主动控制来实现动态误差系统非线性项和线性项的近似解耦，然后通过有限时间稳定理论和自适应控制技术来实现驱动－响应系统的混沌同步。通过仿真，验证本文所提控制策略的正确性和有效性。
