摘　　要：以混沌运动的永磁同步电机作为节点构建线性耦合的复杂动力网络,研究了网络中众多电机的同步控制方法.该方法根据线性耦合网络全局同步的牵制控制条件,设计出电机交轴和直轴电压的比例调节控制器,并给出施加牵制控制后电机网络的状态方程.模拟结果表明:在网络耦合强度、电机节点参数时变情况下,对于小世界拓扑或无标度拓扑构建的电机网络,一个电机节点的线性反馈牵制控制就能实现网络所有电机同步,控制方法具有控制效率高、代价小、可调节等优点.Identical permanent magnet synchronous motor（PMSM） systems,with chaotic characteristics,are selected as nodes to construct a linearly coupled complex dynamical network,and a synchronous control method for realizing the synchronization of PMSM networks is studied.This method designs the proportional controller for adjusting direct-and quadrature-axis stator voltage of PMSM,and presents the status equations of pinned networks based on global synchronous conditions of pinning control linearly coupled networks.Simulation results show that complex dynamical networks with the small-world or free-scale topology can be synchronously controlled to homogenous solutions via pinning a single node with a linear feedback controller,even if the coupling strength of networks and dynamic parameters of PMSM system are time-variable.This synchronous control method of motor networks has some advantages of adjustability,high efficiency and low cost.
