Sensorless Rotor-Field Oriented Controlled Induction Motor Drive with Particle Swarm Optimization Algorithm Speed Controller Design Strategy

Abstract EN

A sensorless rotor-field oriented control induction motor drive with particle swarm optimization algorithm speed controller design strategy is presented.

First, the rotor-field oriented control scheme of induction motor is established.

Then, the current-and-voltage serial-model rotor-flux estimator is developed to identify synchronous speed for coordinate transformation.

Third, the rotor-shaft speed on-line estimation is established applying the model reference adaptive system method based on estimated rotor-flux.

Fourth, the speed controller of sensorless induction motor drive is designed using particle swarm optimization algorithm.

Simulation and experimental results confirm the effectiveness of the proposed approach.
