Fuzzy Control of Doubly Salient Permanent-Magnet

As a new type motor, the doubly salient permanent magnet (DSPM) motor is getting more and more attention this years. DSPM motor has the high nonlinearity between speed and current or torque, so it is difficult to tune the parameters and get satisfied control characteristics by using normal conventional PI controller. This paper provided a new effective method fuzzy control. It showed the model firstly, and then designed a adaptive fuzzy controller based on the motor characters and theory of fuzzy control. The fuzzy had the ability to satisfy control characteristics and it was easy for computing. To test the validity of the design, Mat lab was used to emulate the motor drive. The results prove better running character and speed regulating of the DSPM motor drive with fuzzy control.
