PURPOSE: A method of predicting the driving current value of an AC motor and an AC motor control system are provided to minimize an error between a predicted driving current value and an actual driving current value, thereby improving the accuracy of setting dead-time.;CONSTITUTION: A current sampling point is determined(S41). Predicted driving current value from the current sampling period is corrected based on the predicted error of the driving current predicted value(S43). Said steps are repeated until an ending signal is generated(S44).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB,DD) No; (CC,EE) Yes; (FF) End; (S41) Current sampling point ?; (S42) Deduce predicted driving current value by using current prediction equation of alternating current motor; (S43) Predicted driving current value from the current sampling period is corrected based on the predicted error of the driving current predicted value; (S44) Ending signal ?
