【摘要】 本文对比研究了速度环采用模糊控制和PI控制的永磁同步电机的多相PMSM磁场定向控制。从仿真结果可以看出,模糊控制的速度响应有明显的稳态误差,而PI控制容易产生超调和振荡。为此,本文提出了速度环采用Fuzzy-PI双模的控制方法,这种方法减少了稳态误差和振荡现象,使多相PMSM运行性能得到了极大的改善。更多还原

【Abstract】 The field-oriented control of Multi-phase PMSM magnet with Fuzzy control and PI control are compared in the paper.From the result of the stimulations,it can be seen that there are steady state errors in the Fuzzy control and overshoot and oscillations in the PI control.The control strategy of Dual-mode Fuzzy-PI is proposed to reduce the steady state error and oscillation.更多还原
