The Speed estimation based on MRAS Induction motor

In the traditional speed sensor speed regulation process, the asynchronous motor is inconvenient to install and maintain, the system is susceptible to interference, and the reliability is reduced. A model based reference adaptive (MRAS) vector control method is proposed to increase the reliability of the motor. Motor speed. In the sensorless vector control algorithm, the flux linkage and the speed estimation are inseparable, so the accurate estimation of the rotor flux linkage is crucial. There are two methods for rotor flux linkage calculation, one is the rotor flux current model on the two-phase stationary coordinate system, and the other is the rotor flux current model in the two-phase rotating coordinate system.
