A novel V/F induction motor control system based on stator voltage oriented method is presented. This scheme includes dead time compensation, stator voltage compensation and anti-oscillation regulation, which can greatly improve the V/F systempsilas performance especially low frequency load capability and fast response capability. Different from conventional V/F methods, all the compensation and regulation are based on stator voltage oriented synchronous rotation frame transformation, which avoid complicated vector calculation and are simple to implement. As only stator resistance needed, this method is almost independent of motor parameters. Experimental results display this scheme has profound applicable value in V/F control driver systems.
