基于 Lyapunov 稳定理论及 LaSalle 不变集定理设计自适应控制器，对两台混沌永磁同步电动机（PMSM）系统进行时滞同步控制。理论证明在控制器作用下两电机误差系统渐近零，即控制策略可实现 PMSM混沌系统的时滞同步。数值仿真结果表明该控制策略的正确性及有效性。研究结果对保证多电机系统协调运行具有重要理论意义及实用价值。

Based on the Lyapunov stability theory and LaSalle invariant principle,an adaptive controller was presented,which can achieve the lag-synchronization of two chaotic permanent magnet synchronous motors.The theoretical analysis and simulation results show that the proposed method is effective and the parameters identification is realized simultaneously.The results provide a useful tip for the coordinated operation of electromechanical systems.
