Fuzzy Direct Torque Control of Permanent Magnet Synchronous Motor

Fuzzy controller is applied to the direct torque control of Permanent Magnet Synchronous Motor in the paper. Both hardware and software based on digital signal processor have been introduced to implement the motor system control. Experimental results show that the proposed fuzzy control logic has lower ripples of the electromagnetic torque and flux linkage, fast response and good robustness for variable parameters and constant switching frequency.
