说明：  基于MATLAB软件的交流永磁同步电机调速系统研究 介绍了一种采用磁场定向理论控制交流永磁同步电机的调速系统，应用现代控制理论对 电机直交轴耦合分量进行了解耦，并利用经典控制理论设计了电流环和角速度环调节器。MATLAB 仿真 结果证明了该方法的有效性，但系统调试时仍需根据具体情况适当调整以得到更理想的效果。(MATLAB software based on the exchange of permanent magnet synchronous motor speed control system introduces a theory of the use of field-oriented control of AC permanent magnet synchronous motor speed control system, the application of modern control theory on DC motor shaft coupling the decoupling components and to make use of classical control Theoretical Design of a current loop and the angular velocity of ring modulator. MATLAB simulation results prove the effectiveness of the method, but the system still need to debug when appropriate adjustments in accordance with specific circumstances in order to obtain better results.)
