Робастифицированное векторное бездатчиковое управление угловой скоростью асинхронного двигателя на основе адаптивного наблюдателя пониженного порядка

Abstract

A novel speed sensorless indirect field oriented control for the full order model of induction motor is presented. It provides local exponential tracking of smooth speed and flux reference signals together with local exponential field orientation, on the basis of stator current measurements only and under assumptions of unknown constant load torque. Proposed solution has improved robust properties with respect to stator and rotor perturbations.
