Abstract
A new adaptive flux observer of induction motor is presented in the paper. The Lyapunov theory is utilized for derivation of the adaptation law of rotor flux angular speed, which acts as unknown parameter in an augmented induction motor model. In the field weakening region, where stray fluxes are comparable with rotor flux magnitude, the air-gap flux stabilization is proposed. An air-gap flux multiscalar model is derived for stator current and air-gap flux vectors and the multiscalar model based nonlinear control of induction motor taking advantages of air-gap flux model is applied. The performance of the proposed sensorless control algorithm is verified experimentally on a DSP-based drive system
