Abstract

When speed-sensorless induction motor (IM) drives are operated in low frequency region, the speed observability will be poor. Particularly, the rotor speed cannot be observed at zero stator frequency. Addressing this problem, a current optimization zero frequency ride-through (CO-ZFRT) method is proposed for speed-sensorless IM drives (SSIMD) in this paper. Firstly, the transfer function of the estimated speed to the estimated speed error is derived, indicating the root cause of the speed unobservability at zero stator frequency. Secondly, the implementation of CO-ZFRT is derived by adaptively modifying the magnetizing current to ensure the observability of speed at low stator frequency, following with the analysis on operating point changes. In addition, a current optimization method is proposed for boundary points selection of active zero frequency crossing to obtain the optimal current performance. Combining the constraints of torque, current and observability, the speed observability and the minimum stator current are taken as the additional optimization objectives to derive the active zero-frequency crossing boundary points. Finally, the effectiveness of proposed method is verified on a 2.2kW IM experimental setup.
