摘  要：永磁同步电动机是一个多变量、非线性、高耦合的系统，而现有的多电机同步控制策略难以满足高精确度的同步控制要求。基于在d-q坐标系下的数学模型,采用id=0的转子磁场定向矢量控制方式，对正弦波永磁同步电机进行建模；基于相邻偏差耦合的控制结构，利用单神经元PID控制方法设计一种结构简单的多电机控制策略。与相邻偏差耦合的传统PID控制策略进行的对比仿真表明,该控制策略具有较高的同步精确度和较强的鲁棒性。

Abstract: Permanent magnet synchronous motor (PMSM) is broadly applied in high precision servo system, but the control performance is influenced by factors such as the plant parameter variations, the external load disturbances, and the uncertainties or nonlinear dynamics, so the existing controller can not satisfy the requests of high-performance control. The mathematic model of PMSM which was set up on the d-q system and the id=0 vector control had been chosen to be the strategy of this system. Relative coupling control strategy was applied，and velocity synchronous compensator was established based on single neuron PID algorithms. The results demonstrate that the single neuron PID speed controller was improved greatly in rapidness and robustness.
