摘　　要：Serious commutation lag occurs when a Brushless DC Motor(BLDCM) operates at high speeds,and this leads to torque decline with ripple.In this paper,an advanced conduction control scheme is proposed which can accelerate the commutation and enhance the torque production remarkably.Besides,an on line adjusting algorithm based on the Golden Section Method is adopted to search the optimal advanced conduction angle.Simulation and experimental results verify the feasibility and effectivity of the scheme proposed.高速条件下 ,无刷直流电动机的电流换向产生严重滞后 ,导致转矩下降并伴随脉动 .采用超前导通控制法 ,可有效加快换向过程 ,改善转矩输出能力 ;并采用改进的黄金分割法寻优 ,在线调整最优超前导通角 .
