By investigating the control system in dual-redundancy rare earth permanent magnet brushless motor(DRREPMBLM)
a mathematic model is established
and a fuzzy control based strategy is adopted to construct an experimental DRREPMBLM rapid response servo system. The results show that the proposed strategy is suitable for 2×1.8 kW DRREPMBLM system operation under various conditions of rated operation
step response and frequency response
and makes the DRREPMBLM system get to speed ratio of 1 312.5
angular acceleration response of 15 000 rad/s
2
and frequency band of 20 Hz.
