Full-Order Stator Flux Observer Based Sensorless Vector Controlled Induction Motor Drives Applying Particle Swarm Optimization Algorithm

A speed estimation approach of vector-controlled induction motor drive based on flux observer that applying particle swarm optimization (PSO) algorithm is presented. The proposed estimation speed scheme using full-order stator flux observer has the advantage of simple structure and facile implementation. The observer gain matrix of the full-order flux observer is designed applying the particle swarm optimization algorithm which acquired exact gain parameters rapidly. Simulation and experimental results confirms the effectiveness of the proposed approach.
