This paper introduces a vector control system for speed sensorless induction motor drive, which we have recently developed. In the introduce vector control system, one induction motor’s rotor speed estimation method based on model reference adaptive identification theory is proposed. The induction motor speed identification system based on the proposed method can estimate the rotor speed of the induction motor. The speed sensorless vector control system based on proposed method in this paper was built with Simulink blocks in Matlab platform. The simulation results indicate that the proposed method could operate stably in whole range of speed with preferable identification precision of rotor speed.

Aimed at the problem of speed identification for the asynthetic motor speed-less sensor vector control system, based on basic equations of vector control and centered by the current model and voltage model of rotor flux linkage, after the establishment of the rotor speed identification module by module reference self-adaptation theory (MRAS), this paper builds the MRAS speed-less sensor vector control system and establishes the system simulation model in Simulink software environment. Simulation results show that: the system has good dynamic and static characteristics and stability. Key words: speed-less sensor; vector control; MRAS; simulation CLC: TM343.2 Document Code:A

Doubly Fed

This paper presents a robust observer for sensorless speed control of doubly fed induction motor (DFIM), based on the slidin mode. In the first step, a model of the doubly fed induction motor fed by two PWM inverters with separate DC bus link is developed. In the second step and in order to provide a robust separate control between flux and motor speed a vector control by field oriented strategy applying a sliding mode regulator was implemented. Finally, speed estimation of a doubly fed induction motor based on sliding mode observer is presented. The simulation tests schow the effectiveness of the proposed method especially in the load disturbances, the change of the refrence speed and low speed. Also the influence of parameter variations will be studied by simulation
