This thesis is to design a DSP-based speed-sensorless driver for an induction motor. The driver schemed with closed loop constant V/F ratio is used as the speed control configuration, and a new integrator with adaptive compensation is derived to estimate motor speed. The developed driver with speed estimator has solved the problems of estimation deviation and stability which was occurred when designed by Indirectly Field Orientation Control method under low speed by 10% of rated speed. The experiments demonstrate the sensorless driver has performance of accuracy and efficiency for speed estimation when motor is operated under the circumstance of low speed range and parameter variation.
