This study proposes the design and implementation details of cascade predictive current‐ and speed‐loop controllers for a dual‐permanent magnet synchronous motor (PMSM) drive system. The systematic design procedures for the proposed cascade predictive controllers are presented here. By using the proposed predictive controllers, the dual‐PMSM drive system can attain superior performance, including good transient responses, good load disturbance responses, good tracking responses, and good robustness. To enhance the output torque of the dual‐PMSM drive system, a maximum torque/ampere control method is proposed. In addition, a detailed analysis of the parameter variations of the drive system is discussed. A digital signal processor, a TMS 320‐F‐2808, manufactured by the Texas Instruments, is used as a control centre that executes the control algorithms. As a result, the hardware circuit is simple. Several experimental results reveal that the proposed predictive controllers perform better than proportional‐integral (PI) controllers in transient responses and steady‐state characteristics. The proposed predictive controllers for dual‐PMSM drive systems, which are also investigated in this study, can be installed in electric vehicles and electric ships.
