This paper proposes an implementation to achieve a regenerative braking control for a dual-PMSM drive system. By using the proposed maximum efficiency searching algorithm, maximum power recovery from the braking control can be obtained. A digital signal processor, TMS 320F 2808, is used to execute all of the control algorithms, including dual-motor driving control, dual-motor regenerative braking...
This paper proposes an on-line maximum efficiency control method for a dual-motor drive system. By using the on-line feedback signals and doing simple computations, the output torque of each motor can be determined. Then, a maximum efficiency operation of the whole system can be achieved. The efficiency of the whole system, which includes motor efficiency and inverter efficiency, is investigated....
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...
Permanent variable transmission (PVT) is a new kind of non-contact power transmission device which has unique advantages for applying in the situations of airproof and small vibration requirements. As the most significant design data, static torque reflects the main transmitting capability of the PVT. Static torque expressions in a novel PVT based on the principle of magnetic permeability modulation...
