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。

AC Permanent Magnetic Synchronous Motor Speed Control System Study Based on MATLAB

Introduction was made to a speed control system of AC permanent magnetic synchronous motor with a kind of field oriented con- trol theory. With application of modern control theory to decouple the coupling variables betweend-qaxis of motor, PI regulators of current rings and an angle speed ring have been designed by using classical control theory. MATLAB simulation results verify effectiveness of the method, but suitable adjustment of the system is still needed to achieve better effect according to actual conditions while the system is debugged.
