摘　　要：讨论了基于高速永磁同步电机的航空宽调速范围的交流伺服系统。该系统的关键技术是低速运行的控制。分析了低速运行时的电流脉动 ,提出了适用的功率电路与控制方法 ,并且讨论了系统结构。最后 。In this paper a wide speed range of AC servo system is discussed, the system is based on a high speed permanent magnet synchronous motor. The key technology is the motor control in low-speed running. In the paper the current ripple is analyzed when the motor runs at low-speed state, a power circuit and the control method are presented and the system structure is discussed. Final the system performance is analyzed with the aid of simulation data.
