Abstract:The design of novel robust speed and rotor flux controllers for a field oriented controlled induction motor drive system is presented in this paper. The controllers are designed in terms of stability and performance criteria through a graphical technique, called loop-shaping, taking into account the effects of external disturbances and motor parameter deviations from the nominal model. Employing experimentally verified models, the controllers are tested using numerical simulations, for a large number of off-nominal parameter values. It is observed that for a doubling of the rotor resistance, the maximum absolute error in the flux magnitude is only 0.01 p.u. A comparison of the proposed controller approach with conventionally used proportional plus integral (PI) controllers indicates that PI controllers do not function in a stable manner even for an increase of 20% in rotor resistance.
