Abstract
The major purpose of this paper is to implement and study the scalar and vector
control on three phase induction motor drives. In scalar control method stator voltage and
frequency ratio kept constant. It is also called V/F control. The scalar method is very
simple controlling method as compare to vector control which is more complex. Vector
control related to phasor control of induction machine. The VCIM drive includes
decoupling of the stator current component which produces torque and flux of induction
motor. In this paper, an implementation of speed control of an induction motor (IM) using
indirect vector control procedure has been developed and simulated. The comparative study
of VCIM and traditional V/F control of IM is done on MATLAB/SIMULINK software.
Results show the effectiveness of vector control over scalar control method.
