Abstract
Stator flux oriented induction motor not only has its continuous control, but also is robust to stator parameters. However, as its torque can not decouple the flux, a decoupler is needed thus adding to the complexity of the system. To settle the coupling problem in flux orientation, it is suggested that a stator flux orientation control mode without decoupler and an extended state observer (ESO) is adopted to compensate the coupled part. Active disturbance rejection controller (ADRC) is used to control the flux loop and speed loop. Simulation and experiment verified the feasibility of the given scheme. It achieves stator circle flux control and the speed adjusting system has fine dynamic and static performances.
