中文摘要：

将自适应逆控制应用于交流永磁同步电机位置伺服系统中，采用最小二乘（RLS）算法建立对象的模型、对象逆模型，并设计了自适应逆位置控制器。研究结果表明最小二乘算法有较快的动态响应和较小的稳态误差，而且系统的抗干扰能力也很强。自适应逆控制的同步电机位置系统具有较好的鲁棒性。

英文摘要：

The algorithm of the adaptive inverse control is first used in the control of, the position system of AC permanent magnet synchronous servo motor（AC- PMSM）, plant model and inverse model are established by recursive least squares . And the adaptive inverse control of position is designed. The result shows that RLS algorithm has better dynamic response and small steady- state error and strong rejection disturb. The position control system based on adaptive inverse control is robust to disturbance and the parametric variation of motor.
