摘要
建立永磁同步电机的数学模型。采用基于励磁电流id=0的转子磁场定向矢量控制方法,实现永磁同步电机的解耦控制。在MATLAB仿真软件环境下建立了交流伺服系统的仿真模型,位置调节器、速度调节器和电流调节器均采用常规PI控制算法,逆变器采用SPWM调制策略。仿真结果验证了控制方案的正确性和有效性。
In this paper,a mathematical model of permanent magnet synchronous motor.Based on excitation current i=0 of the rotor d flux-oriented vector control method to realize the decoupling control of permanent magnet synchronous motor.In the MATLAB simulation software environment was established under the AC servo system simulation model,location,regulator,speed regulator and current regulator are the conventional PI control algorithm,inverter using SPWM modulation strategy.The simulation results verify the correctness and effectiveness of control programs.
