An LPV control scheme for induction motors

The paper is concerned with the design of a linear parameter varying (LPV) regulator for controlling the shaft angle and speed of an induction motor. The design is based on recent results concerning LPV systems and ensures stability independently of how the shaft angular velocity, chosen as the varying parameter, changes in time within a suitable compact set. The LPV control system structure consists of two nested loops: an inner stator current loop, and an outer torque and shaft angle loop. The suggested technique is applied to a benchmark motor model taken from the literature on the control of induction motors. Simulations show that the suggested control system performs well. © 2012 IEEE.
