Vector Control System for Speed-Sensorless Asynchronous Motor Based on btPO~S Flux observation and Speed Estimation

Aim to the problems that the traditional vector control system＇s flux observation was not accurate and needed speed sensor,based on MRAS flux observation and speed estimation, the vector control system for speed-sensorless induction motor was proposed in this paper.The MRAS structures of flux observation and speed estimation were introduced and the Popov hyperstability theory was used to deduce the corresponding adaptive laws.The the experimental simulation system was set up and the experimental results showed that the vector control system run with good static and dynamic performance at time of its starting,speed regulating and steady-state operating and is a high-performance AC speed regulation system.
