【摘要】：针对永磁同步电机(permanent magnet synchronous motors,PMSM)在弱磁区电动工况下运行时动态性能不理想的问题,依据PMSM弱磁理论,研究了dq轴电流调节器对弱磁动态性能的影响,提出一种改善PMSM动态性能的弱磁策略。弱磁电流由q轴电流误差积分器和电压调节器共同作用获得。仿真和实验结果表明该策略抑制了q轴电流调节器的不利影响,改善了PMSM在弱磁区电动工况下的动态性能,同时具有抗积分饱和及弱磁控制的双重功能。
[Abstract]:In order to solve the problem that the dynamic performance of permanent magnet synchronous motor permanent magnet synchronous motor is not ideal under the condition of weak magnetic field, the effect of DQ axis current regulator on the dynamic performance of weak magnetic field is studied according to the theory of PMSM weak magnetic field. A weak magnetic field strategy is proposed to improve the dynamic performance of PMSM. The weak magnetic current is obtained by the interaction of the q-axis current error integrator and the voltage regulator. The simulation and experimental results show that the strategy can suppress the adverse effect of the q-axis current regulator. It improves the dynamic performance of PMSM under the condition of weak magnetic field and has dual functions of anti-integral saturation and weak magnetic control.
