摘要
提出了一种新的飞机用无刷直流电动机的系统建模方法,该模型可以实现电机性能、故障保护、软起动的综合仿真。根据无刷直流电动机的数学模型,在Matlab 2010a的Simulink环境下,采用S函数和模块化建模方法,建立了相应的系统仿真模型。为提高可靠性,较详细地讨论了过流、欠压和缺相故障的保护。仿真实验结果与理论分析一致,验证了模型的合理有效性。
A novel method for modeling and simulation of the brushless DC motor system for Aircraft was presented. With this model, all the simulation of motor performance, fault protection, soft start can be realized. The mathematic model of the BLDCM was established. Under Simulink in Matlab 2010a,the simulation model of the BLDCM system can be modeled by the S-functions programming and modular design. Over-current, under-voltage and open phase protection were discussed to improve reliability. The reasonability was testified by the coincidence of the simulation results and theory analysis.
