PREDICTIVE CURRENT CONTROLLER OF THE VECTOR-CONTROLLED ASYNCHRONOUS MOTOR
Igor Bélai - Milan alman
In this paper a controller of both the flux and torque components of the
stator current vector of an asynchronous motor is described. The current
controller is composed of two parts: the predictive and the PI components.
The controller output is the reference stator voltage vector generated
via PWM. The effect of the predictive component becomes apparent mainly
in transient states improving control dynamics. PI component decreases
the sensitivity of the current vector control to the motor parameter
deviation. The method supports software implementation.
