Adaptive Control of Induction Motors
Controller design techniques for induction motors were presented in Chap. 12 assuming knowledge of all motor parameters. However, this is often not a valid assumption in practice. The parameters that are particularly prone to uncertainty and dependence on operating conditions are load torque and rotor resistance. The rotor resistance may vary up to 100% during operation due to rotor heating. Furthermore, output feedback designs that do not utilize flux measurements are desirable since flux sensors are expensive and are typically not available.
