摘要
In this paper a sensorless vector control scheme for induction motor, which works in a whole range of speed, is presented. Controller is based on a low order and semiglobal convergence new observation algorithm which simultaneously estimates fluxes and rotor speed with constant and unknown load. Performance of sensorless field oriented controller proposed is verified by means of numeric simulation for tracking of variable speed including the zero speed and it is compared with obtained results for the same control scheme based on model reference adaptable system observer.
