Application of localization control in drive system with induction motor

This paper presents an electric drive frequency-control system with inductions squirrel-cage motor, working in the conditions of achieving maximal electromagnetic torque values. In the conditions of a limiting work the parameters of the motor are changed by the saturation of the magnetic circuits of the motor. There are great signal disturbances working on the side of the supply network and also on the side of the motion work. To provide a robust of the control of the drive system on the parametric and signal disturbances we use a method, which bring in an inner-control circuits, which are derivatives of state variable - which is said to be a localization method. The paper presents results of the stimulation calculations for the drive which has a power of 5,5kW.
