摘　　要：基于带抽头电感的准Z源网络,构建一种永磁无刷直流电机(BLDCM)的控制系统。利用该准Z源网络的高电压增益特性,实现两种工作模式的平滑切换,有效拓宽了无刷直流电机控制系统的调速范围,并弥补了电源端故障时电机转速和转矩特性变差的问题。仿真和实验证明了该方法的有效性、准确性和实时性。A novel brush-less DC motor control system based on tapped-inductor quasi-z-source converter was proposed. Smooth switching of two modes in the proposed system could increase speed range by utilizing the DC high voltage gain charactetistic,effectively solve the problem of small speed range and optimize the degraded performance of speed and torque in existing BLDCM control system. The simulation results of PSIM are analyzed in detail and demonstrate the validity of the proposed control system.
