摘　　要：双转永磁无刷直流电动机作为螺旋桨推进电机,广泛应用于无人水下航行器。基于双转永磁无刷直流电动机工作原理,建立电机数学模型,采用变参数PI控制算法设计控制器,给出相对位置检测的换相控制方案,在Matlab平台上,建立电机调速系统仿真模型。仿真结果表明,仿真建模准确,控制算法精确、稳定、可靠。The dual-rotor permanent magnetic brushless direct current motor（dual-rotor PMBLDCM） which has two rotors running in opposite direction at any time is widely used in autonomous underwater vehicle as the driving motor of propeller.Based on the working principle,this paper built the mathematical model of dual-rotor PMBLDCM,designed controller adopting variable parameter PI control algorithm,gave a phase-change control scheme employing relative position detection and built the simulation model of the speed regulation system of dual-rotor PMBLDCM under Matlab platform.The simulation result proves that the simulation modeling and algorithm of controlling are accurate,stable and reliable.
