Requirements for the implementation of rotation speed estimators for induction machine field-oriented control in FPGA

Završni rad obuhvaća obradu najzastupljenijih metoda estimacije brzine vrtnje asinkronih strojeva, simulaciju odabrane metode estimacije i provedbu diskretizacije opisnih jednadžbi sustava indirektnog vektorskog upravljanja bez senzora brzine potrebnu za implementaciju u digitalno sklopovlje. Kroz simulacije je demonstrirana kvaliteta estimacije brzine vrtnje asinkronog stroja pomoću odabranog estimatora za širok raspon brzina.In this final paper, the most prevalent methods of estimating an induction motor's rotational speed are presented, a selected method is simulated and the equations which describe a sensorless indirect field-oriented control system constructed using the selected estimator are discretized for implementation in a FPGA circuit. The simulation results demonstrate the selected estimator's ability to accurately estimate the rotational speed of an induction motor operating in a wide speed range
