关于无刷电机FOC驱动算法的研究

AbstractIn recent years,the high-tech industry has developed rapidly,and a lot oftechnical products have been produced along with it.Brushless dc motor is thecore part of many technical products,covering various high-tech fields such astransportation vehicles and industrial equipment.Compared with traditionalcontrol methods,FOC has the characteristics of high efficiency,low noise andfast response.Therefore,FOC algorithm has developed rapidly in recent years.This paper mainly proposes an algorithm to control the brushless dc motor.Through the frame design of the brushless dc motor control system,it tries touse STM32 to achieve the FOC drive control panel,and then deduces the mainformula of the FOC control algorithm.The brushless dc motor is controlled byFOC algorithm,which not only avoids the shortage of the traditional brushlessdc motor control algorithm,but also improves the operation efficiency of themotor system.In addition,FOC combined with sensorless algorithm improvescontrol efficiency,reduces process cost and increases application scope.Keywords:FOC;BLDCM;STM32;Sensorless;Motor Parameter
