Abstract :
A maximum efficiency control for a dual-motor drive system is presented in this paper. The torque sharing between two motors is optimized by using the perturbation and observation method. A fuzzy-logic controller is implemented for the perturbation and observation method. As a result, the step of perturbation can be adaptively modified to improve the performance. In addition, a simple calculation is used to achieve real-time efficiency measurement. The proposed method is implemented on two identical 2 kW permanent magnet synchronous motors connected in parallel. Finally, experimental results validate the proposed control scheme performance.
