Abstract
As a widely used power component of unmanned aerial vehicle, the direct current (dc) brushless motor has the prominent advantages of high efficiency, long period, low noise, and better speed–torque. In this paper, a novel parameter design method is presented for a dc brushless motor. To maximize the efficiency of the power system, the pigeon-inspired optimization algorithm is utilized by converting the dc brushless motor parameter design problem to an optimization problem. A modified model is proposed to avoid falling into the local optimal value and increase the population diversity by introducing the adjacent-disturbances and integrated-dispatching strategies. Comparative experiments are conducted to verify the convergence speed and the effectiveness of the proposed method.
