Abstract

The induction motor is represented by nonlinear equations whose parameters are changing with respect to the slip-frequency, temperature, etc. The slip-frequency is effected by unknown load which is difficult to estimate on-line. Astable vector controller is designed with direct MRAC to improve the quality of the transient response. The unknown load is considered in this speed controller design, and tested by simulation. Also a flux controller is designed and tested to reduce the audible noise in this paper.
