摘　　要：为深入研究冗余无刷电动舵机系统,在建立双余度无刷直流电动机(DR-BLDCM)数学模型的基础上,利用Matlab/Simulink搭建了其伺服系统的仿真模型。模型采用模块化的设计方法,电机反电动势由分段线性法产生,提高了系统的准确性和有效性。仿真结果证明了该模型的有效性,研究为电动舵机系统设计提供了思路。To study dual-redundancy rudder servo system in depth, based on the mathematical model of the dual-redundancy BLDCM, simulation model of this servo system was established by means of Matlab/ Simulink. The modeling adopted the method of modularization, the back-EMF was generated using piecewise linear curves and the accuracy and effectiveness of the system was improved. The reasonability and validity have been testified by the simulation results and the model offers a thoughtway for designing actual servo system.
