做项目的时候在ST的库上加死区补偿,整理了一些前期做的准备工作内容,上传的是压缩的PDF文件。有需要的可以看看,不是成品,不是程序,只是一点点想法。(The theory of dead time compensation in motor control. The file is a PDF. it is only the comprehension of myself about this function.)
Sensorless Detection of Rotor Position of PMBL Motor at Stand Still
针对感应电机矢量控制系统,提出了一种可以同时补 偿死区误差电压并消除零电流钳位现象的死区补偿方法。在分析影响死区效应的因素以及等效死区时间表达式的基础上,采用平均死区时间补偿法,在两相静止轴系中对等效死区时间产生的误差电压进行了补偿。为了提高电流极性检测的准确性,利用旋转轴系中的励磁电流和转矩电流分量经过 坐标反变换,判断电流在两相静止轴系所处的扇区来决定需 要施加的补偿电压。(A dead—time compensation strategy is presented to compensate dead time elTor voltage and eliminate zero·- current clamping effect for vector controlled induction motor drive system.The factors influencing dead·time effect are analyzed,and expression of equivalent dead time is deduced.Average dead·time compensation technique is adopted to compensate error voltage at two—axes stationary frame.To improve accuracy of current polarity detection,components of magnetizing current and torque current are transformed into two-axes stationary frame.Therefore,compensating voltage vector Can be determined according to the sector where the current vector locates.)
