| Sumario: | Based on a hybrid excitation generator, a novel electric vehicle range-extender was proposed and the control system structure and the working principle were described. The multi-speed point working area was determined, according to the overall efficiency characteristics of the hybrid excitation range-extender. Based on the flexible adjustable characteristics of the air-gap magnetic field of the hybrid excitation generator, a double-closed-loop generation control algorithm was designed by decoupling the speed-power around the working area of the range-extender. The control strategy model was built by using MATLAB/Simulink and verified based on the prototype of the self-developed hybrid excitation range-extender. The test results show that the hybrid excitation range-extender has fast-dynamic response of output power and small steady-state error of speed and power control. Further, the steady-state and transient operating conditions are both located in the set working area. Therefore the power generation control strategy is feasible. |
