INDUCTION MOTOR
no vote
INDUCTION MOTOR VARIABLE SPEED CONTROL WITH MATLAB COADING PRESENTED HERE. Several field-oriented induction motor drive methods  without rotational transducers have been proposed. These methods have a disadvantage that the rotor resistance variation  causes an estimation error of the motor speed. Therefore, simultaneous  estimation of the motor speed and the rotor resistance  is required. This paper presents a method of estimating simultaneously  the motor speed and the rotor resistance of an induction motor by superimposing ac components on the field current  command. The validity of the proposed method is verified by&nb
