摘要已有研究表明，电机在某些参数及工作条件下会出现混沌振荡行为。另一方面，现代工业生产过程中，经常需要多台电机协调同步运行。当前，国内外对电机系统、网络的混沌振荡同步分析与控制已有较多研究，但对电机系统、网络由于参数扰动引起同步中断的分析与控制研究尚属少见。为此，在传统的扩散耦合方式基础上，通过引入单向交叉耦合方式，研究了永磁同步电机（PMSM）系统、网络受到参数扰动后的振动特性。分析并证明了单向交叉耦合对PMSM系统、网络的参数扰动具有同步鲁棒性；并以3节点、4节点和一个多节点网络的PMSM系统验证，交叉耦合对多节点电机网络全局稳定同步的重要作用。研究结果表明，通过建立合适的单向交叉耦合方式，能够有效控制电机网络因参数扰动而引发的同步中断，使同步中断得以重新恢复。

Abstract：Previous studies showed that chaotic oscillation behavior occurs in a single motor under some certain parameters and operating conditions. On the other hand, in the modern industrial production process, multiple motors are often required to operate in coordination and synchronization. At present, there are many studies on chaotic oscillation synchronous analysis and control of motor systems and networks at home and abroad, but investigations on synchronous interruption analysis and control of motor systems and networks due to parametric disturbance are less. Here, on the basis of conventional diffusion coupling mode, vibration characteristics of permanent magnet synchronous motor (PMSM) systems and networks after parametric perturbation were studied by introducing a unidirectional cross coupling mode. It was proved that unidirectional cross coupling has synchronous robustness to parametric perturbation in PMSM systems and networks. PMSM systems with 3-node, 4-node and multi-node networks were adopted to verify cross coupling having important actions of global stability and synchronization for multi-node motors and networks. The study results showed that establishing a suitable unidirectional cross coupling mode can effectively control synchronous interruption caused by parametric disturbance in motor networks, and recover their synchronous operating.

Key words： permanent magnet synchronous motor (PMSM) synchronous interruption cross coupling chaotic synchronization
