Design and implementation of predictive controllers for dual-PMSM drive systems

This paper investigates design and implementation of a predictive controller for dual-PMSM drive systems to improve output torque and dynamic responses. Experimental results show the dual-PMSM drive system has satisfactory performance, including good transient responses, load responses, and tracking responses. In addition, when one PMSM drive fails, the other PMSM drive still can provide output torque. The digital signal processor, TMS320-F2808, is used to execute the entire algorithm. The proposed method can be applied for electric vehicles or electric ships.
