Sensorless control using the model reference adaptive control estimator in electric drives with high dynamic

In this article we'll tackle the control of electric drive with high dynamic, with rapid changes in torque and speed, where the control strategy is FOC (Field Oriented Control). Such cases were dealt with where speed is measured directly with an encoder, compared with the case of sensorless control, where speed is estimated using a Model References Adaptive Control Estimator. Simulations were carried out in MATLAB/Simulink environment, highlighting the control structures and comparative results achieved for a drive application commonly used in surface mining industry.
