Velocity-Current Double Closed-Loop Control Model and Simulation of BLDCM in Pure Electric Vehicle Applications

Abstract:

Traditional control models of BLDCM, in which only the internal parameters of motors are considered, have some shortcoming in smoothing the vehicle velocity. To achieve a better controlling capability, a velocity-current double closed-loop control system model for BLDCM of PEV is constructed on Matlab, in which the inner current loop is for quickly adjusting BLDCM’s actions, the outer velocity loop is for an optimized control of PEV’s speed. The results of a simulating experiment show that the new model has a good performance and a strong anti-interfere ability. Therefore, this model is applicable for designing and debugging of BLDCM in PEV applications.
