ABSTRACT
In order to improve the efficiency of the driving system of the urban electric buses, the three-phase asynchronous motor loss model was established, the relational expression of the optimal flux, parameter, angler speed and the torque of motor was deduced based on the loss model on the basis of orientation vector control and simulations based on the optimal efficiency model which were about the loss model of the motor of the urban electric bus were carried out in MATLAB/Simulink and the motor efficiency with non-optimum is 62.95%, while the optimized efficiency is 84.23% based on the loss model optimization; finally, to verify the practicability of the method, the simulation experiment with real vehicle was carried out and the mean efficiency of the motor was improved from 59.93 to 82.45%. The results showed that the rapider control response and global optimal efficiency could be achieved by this method compared with normal vector control method.
