中文摘要：

交流伺服电机广泛应用于机器人控制、数控机床等对调速系统性能要求很高的领域。在高性能数控机床、机器人等领域应用的交流伺服电机几乎都需要配置光电编码器等位置反馈元件,其控制多采用矢量控制的方式。但是由于系统误差和运行过程中的机械变形和装配原因,电机控制性能往往难以满足要求。为此,提出一种永磁同步电机（PMSM）多传感器组合全闭环矢量控制方法,并且重点比较了PMSM传统矢量控制方法和PMSM多传感器组合全闭环矢量控制方法。通过分析比较,试验结果展现出PMSM多传感器组合全闭环矢量控制方法可以很好地提高伺服系统的动态、稳态精度。

英文摘要：

AC servo motor was widely used in robot control, numerical control machine tools for high speed control system performance requirements, the high performance CNC machine, robot in areas such as almost all of the application of ae servo motor need to configure the position feedback components such as photoelectric encoder, its control method with the method of vector control. But because the system error and cause mechanical deformation and assembly in the process of operation, and motor control performance was often difficult to meet the requirements. A kind of permanent magnet synchronous motor multi-sensor combination full closed-loop vector control method was put forward and analyzed. And focusing on the traditional permanent magnet synchronous motor vector control method and the permanent magnet synchronous motor muhi-sensor combination full closed-loop vector control method. Through analysis and comparison of the experimental results showed a multi-sensor combination full closed-loop vector control method could well improve the servo system of dynamic and steady-state accuracy.
