Abstract:
Vector control schemes are increasingly used in induction motor drive
systems to obtain high performance. However, in order to implement the
vector control technique, the induction motor speed information is required.
Different speed sensors are used to detect the speed. But in most applications,
speed sensors have several problems. These problems are eliminated by speed
estimation by using different speed estimation algorithms. Out of which,
model reference adaptive system techniques are one of the popular methods to
estimate the rotor speed due to its good performance and simplicity. Each
technique has advantages and drawbacks. In this project, the induction motor
with rotor flux based model reference adaptive system rotor speed estimator is
designed and validated through MATLAB/SIMULINK software package.
The results of simulations show that the performance of the speed estimation
is very good. The high performance of the proposed control scheme under
different speed commands, load disturbances and parameter uncertainties is
also demonstrated via simulation results.
