چکیده
A physcial approach is employed to estimate the rotor flux for a position sensorless induction machine drive system. This approach i s based on the fundamental operating characteristics of the induction machine. The estimator structure calculates the rotor flux accurately at low speeds, and as laryely insensitive to parameter variations. System structure, theoretical analysis, simulation, and laboratory results are presented.

The rotor flux is estirnatcd for a direct field oriented induction machine drive using a voltage-current mode algorithm, or physical based algorithm. The estimated rotor flux is used to synthesize the components of the rotation matrix, szn(@,) and cos(@,). These angles are critical in transforming the command currents to the stationary frame such tha t field orientation is maintained. The princ...

This paper presents a new adaptive Sliding-Mode flux observer for speed sensorless and rotor flux control of three-phase induction motor (IM) drives. The motor drive is supplied by a three-level space vector modulation (SVM) inverter. Considering the three-phase IM Equations in a stator stationary two axis reference frame, using the partial feedback linearization control and Sliding-Mode (SM) c...

متن کاملSensorless field orientation control of induction machines based on a mutual MRAS scheme
A mutual model reference adaptive system (MRAS) is proposed to implement a position sensorless field-orientation control (FOC) of an induction machine. The reference model and adjustable model used in the mutual MRAS scheme are interchangeable. Therefore, it can be used to identify both rotor speed and the stator resistance of an induction machine. For the rotor speed estimation, one model is u...

This paper proposes a new sliding mode control (SMC) based model reference adaptive system (MRAS) for sensorless indirect field oriented control (IFOC) of a single-sided linear induction motor (SLIM). The operation of MRAS speed estimators dramatically depends on adaptation mechanism. Fixed-gain PI controller is conventionally used for this purpose which may fail to estimate the speed correctl...
