High-performance vector control without AC phase current sensors for induction motor drives: Simulation and real-time implementation

The main purpose of this paper is to develop a high-level performance, and low-cost current sensorless control strategy for Induction Motor (IM) drives. Therefore, new phase-current regeneration method, vector in induction motor drives introduced. idea based on the reconfiguration Luenberger adaptive observer currents estimation, using information provided by dc-link voltage sensor. basis proposed theoretical study modified are presented. Several simulation experimental tests were performed an 1.1 kW working under different operating conditions. obtained results prove testify relevance, workability, practicability suggested strategy.
