Opis:: This paper deals with the stability problem of three stator current error-based estimators of induction motor speed, especially in the regenerating operation mode. The stability of the adaptive full-order observer (AFO) and two model reference adaptive systems (MRASs) based on a stator current error (MRASCC and MRASCV) is briefly analysed, and the stability borders are determined and compared. It is shown that MRASCV speed estimator is stable in the whole operation range including the regenerating mode without any modifications. The stability enhancement method for AFO and MRASCC estimators is described, and the solution for their stability improvement is proposed. Torque-speed characteristics of the analysed MRAStype estimators in a wide range of drive speed and load torque changes are given, as well as the behaviour of estimators during transients is compared. The theoretical analysis and simulation test results are validated by experimental tests.

Opis:: This paper deals with the stability analysis of MRAS current speed estimator in a motoring and regenerating mode. The unstable operating points of the estimator, mainly in a regenerating mode are widely discussed. The expanded version of the estimator MRASCC is proposed to provide its stability in the whole operating range. The new correction coefficients for two analyzed stabilization methods are proposed. Finally, simulation results confirming the theoretical analysis are presented.

Opis:: The paper presents the principle of operation and block diagrams of different, modified MRAS-type estimators of the induction motor rotational speed. A Luenberger observer with additional integrators is used for reconstruction of magnetic fluxes in the adaptive model of the considered estimators. In the presented estimators the measurable currents of the stator winding are applied to generation of a speed tuning signal. For stator winding current reconstruction in the adaptive model there are used the Luenberger observer output signals. Moreover, in the paper there are presented the results of simulations and laboratory investigations of the described estimators operating in a multiscalar control system. For comparison, the results of similar investigations performed for a MRAS-type estimator designed basing on the so-called current model of magnetic flux estimator are given as well.

Tytuł:: Performance analysis of the sensorless adaptive sliding-mode neuro-fuzzy control of the induction motor drive with MRAS-type speed estimator

Opis:: This paper discusses a model reference adaptive sliding-mode control of the sensorless vector controlled induction motor drive in a wide speed range. The adaptive speed controller uses on-line trained fuzzy neural network, which enables very fast tracking of the changing speed reference signal. This adaptive sliding-mode neuro-fuzzy controller (ASNFC) is used as a speed controller in the direct rotor-field oriented control (DRFOC) of the induction motor (IM) drive structure. Connective weights of the controller are trained on-line according to the error between the actual speed of the drive and the reference model output signal. The rotor flux and speed of the vector controlled induction motor are estimated using the model reference adaptive system (MRAS) – type estimator. Presented simulation results are verified by experimental tests performed on the laboratory-rig with DSP controller.
