摘要
A method for estimating a speed and a rotor magnetic flux of an induction motor according to the present invention is a method for estimating a speed and a rotor magnetic flux of a induction motor by using a variable to be used in a main rotor flux estimator or sub- Calculating a value of the first parameter; Estimating a current rotor flux at an immediately preceding interrupt period using software of the computer system; Estimating a speed of the induction motor in the current interruption cycle using the estimated current magnetic flux; Selecting one of the main rotor flux estimator and the sub rotor flux estimator using the rotor flux estimate and the speed estimate to estimate the rotor flux of the induction motor in the next interrupt period of the current interrupt period ; And estimating a rotor flux at a next interrupt period of the current interrupt period by the selected main rotor flux estimator or sub-rotor flux estimator.;According to the present invention, since the switching operation method of two algorithms having different convergence regions is used, the speed and rotor flux of the induction motor can be accurately and quickly estimated regardless of the speed region or the load condition.
