在标量控制中,仅对电机的基本物理量,如电压、电流、磁通等进行控制,而不涉及电机的矢量参数。该控制方法的优点在于简单易实现,但缺点是其控制精度有限,控制效果不够优异。
矢量控制是指直接对电机的磁通、电流进行控制,实现对电机的转矩、转速、位置等参数的控制,从而实现对电机的控制。在矢量控制中,可以根据电机转子位置和磁极数来计算出电机的转矩和转速,并通过调整电机电流、电压和频率等参数来控制电机的运行状态,从而达到的控制效果。矢量控制器适用于复杂负载要求高的场合,如电动汽车、电机数控等电机控制应用。
在矢量控制中,除了控制电机的基本物理量外,还对电机的矢量参数进行控制,如转子磁场定向、电流矢量控制等,从而可以更地控制电机的转速和转矩,并且可以实现、的控制效果。矢量控制主要包括感应电机矢量控制和永磁同步电机矢量控制两种。
