摘要
传统的直流无刷电机数学模型建立在电动机两两导通的基础上,而实际上由于电动机中性点悬空,不可避免存在三相同时导通的情况。介绍直流无刷电机的工作原理,在分析无刷直流电机数学模型的基础上,用Matlab建立无刷直流电机控制系统的仿真模型,并详细论述控制系统的各个子模块。通过对实例电机的仿真,给出仿真结果,验证提出的控制方法有合理性和可行性。
The traditional BLDCM mathematical model establishment in the electric motor two- phase breakover foundations, in fact the neutral point is hanging, inevitable existence three - phase breakover at the same time. This article in the multianalysis BLDCM＇s principle of work foundation, established one kind of new BLDCM control system simulation model based on the analysis of the mathematic model of the BLDCM, introduced the subsystems＇ model of the control system in detail. The feasibility and rationality of control system design are proved by the simulation result.
