【 摘 要 】

In this thesis, a robust adaptive control scheme is proposed in order to drivean induction motor with high performance, even in the presence of unknownmachine electrical parameters. Magnetic saturation within an inductionmotor results in nonlinear, changing flux dynamics. Also, rotor resistancechanges with temperature as the machine is heated due to normal use, resulting in more parametric uncertainty. The proposed control scheme willcause the motor to track a desired reference model behavior, even in thepresence of these unknown parameters. An adaptive control scheme knownas L1 adaptive control is used to ensure that this reference model behavior is realistic, so that robustness may be maintained even with very fastadaptation. This controller is limited by the flux observer used to provideinformation about flux magnitude and direction.
