Servo drive applications require fast dynamic responses. Modern power electronics and Microcomputers enabled high performance ac drives for this purpose and the induction motor cage type is the most commonly used in adjustable-speed ac drive systems because of its robustness and low-cost. Vector control of an induction motor surpasses the performance of a direct current motor but the control method is inherently complex. The indirect vector control method, used in the present work, has a problem of performance degradation due to parameter variations, mainly rotor time constant, which is used in the slip gain calculation. An adaptive observer of an induction motor with a parameter adaptive scheme is proposed for tuning the slip gain calculation, in the present work. The system simulations were performed using Matlab/Simulink software to demonstrate its effectiveness. An experimental study with assembly software implementation was carried out, by using of a Texas Instruments DSP board.
