Abstract :
A parameter-insensitive drive system that utilizes the outer-loop sliding mode control and inner-loop decoupling control of a series-connected wound rotor induction machine (SCWRIM) is presented. The methods of decoupling control and torque linearization for the SCWRIM are outlined. Sliding mode control with cascaded integral operation is used to provide invariant speed response, improved steady-state accuracy, and reduced torque chattering. The scheme is implemented using a resolver-based system for speed and position sensing. The parameter-insensitive characteristics are demonstrated through computer simulations and experimental verifications
