Adaptive Vector Control of Induction Motor Drive
2020 7th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE), 2019Modern induction electric drives usually use vector control, due to which their characteristics are improved. The purpose of most studies are the problems associated with the identification and estimation of the parameters of electric drives at zero speed and close to it. The article proposes an adaptive control in the control loop of the torque.

An observer for speed sensorless induction motor drive
Proceedings of 1994 IEEE International Symposium on Industrial Electronics (ISIE'94), 2002An observer for a speed sensorless induction motor drive is proposed in the paper. It is easy to implement on a microprocessor with particular reference to high performance drives requiring the vectorial control technique which needs a flux observer. The proposed speed observer is based on an adequate arrangement of the error system equations, written ...

A model reference identification technique for induction motor drives
Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 2002Real-time identifiers of the rotor parameters of an induction motor drive are presented in the paper. The synthesis procedure of the identifiers is based on the MRAC system theory. An appropriate choice of the reference model allows a Lyapunov function to be built up by means of which the updating law of one of the above mentioned parameters can be ...

Adaptive Learning Control for Induction Motor Servo Drives
2007 IEEE International Symposium on Industrial Electronics, 2007The output feedback tracking control problem for induction motor servo drives with mechanical uncertainties is addressed. Under the assumption that the reference profile for the rotor angle is periodic with known period, an adaptive learning control is designed, which "learns" the non-structured unknown periodic disturbance signal due to mechanical ...

On line estimation of speed and parameters in induction motor drives
ISIE '97 Proceeding of the IEEE International Symposium on Industrial Electronics, 2002An algorithm which performs the simultaneous online estimation of motor speed and two motor parameters in induction motor drives is presented in the paper. Therefore, speed sensorless control is made feasible. The proposed algorithm is based on a full order flux observer and on the analytical relation which links the error on the stator current to the ...
