STATES AND PARAMETERS ESTIMATION OF THE ASYNCHRONOUS MACHINE BY USING THE OPTIMAL OBSERVERS. PART I – ESTIMATION OF THE FLUX COMPONENTS BY USING A LUENBERGER OBSERVER

Abstract

THIS PAPER DISCUSSES THE ASYNCHRONOUS MACHINE FLUX ESTIMATION BY USING A COMPLETE ORDER ESTIMATOR (LUENBERGER ESTIMATOR). THERE IS PRESENTED THE STRUCTURE OF THIS OPTIMAL OBSERVER TYPE AND THE NUMERICAL IMPLEMENTATIONS ALGORITHM. IT IS PERFORMED THE TIME-DISCRETE STATE-SPACE MODEL OF THE ASYNCHRONOUS MACHINE AND THE ALGORITHM FOR THE NUMERICAL IMPLEMENTATIONS OF THE LUENBERGER STATE ESTIMATOR. THE ESTIMATOR OF THE ROTOR AND STATOR FLUX IS SIMULATED USING THE MATLABSIMULINK FILES. FINALLY, THE CONCLUSIONS OF THIS ESTIMATOR STUDY ARE PRESENTED.
