Abstract:Variation of parameters and nonlinear commutation process limit the speed control performance of brushless DC motor(BLDCM). A control approach based on neural network inverse system was developed for the brushless DC motor by analyzing the mathematical model in conduction region and commutation region. The inverse system of BLDCM consists of a static artificial neural network (ANN) and two integrators. By cascading the inverse system with BLDCM, the nonlinear system was transformed into pseudo-linear system and the whole system performance is improved. Simulation and experimental results show that the proposed scheme reduces overshoot, preserves fast speed response merit, and shows robust to load disturbance and motor parameters uncertainty. It effectively improves dynamic and static operation performance, and is a novel control method for BLDCM.
