Filed: 1993-04-05
Abstract: PURPOSE:To obtain the large gain of a control system and make a detected current value used in digital current control agree with an instructed current value by a method wherein an estimated current value calculated taking the delay of a calculation time into account is used as the detedted current value. CONSTITUTION:The current values of the respective phases of an induction motor 9 are detected by current sensors 8, inputted to the current detectors 7 of a current control part and converted from analog values into digital values. Then, in current estimating devices, deviations between the present digital current values and the previous digital current values are multiplied by a constant and the multiplied values are added to the present digital current values and the resultant values are used as estimated current values. Then, deviations between instructed current values of (u), (v) and (w) phases and the estimated current values of the respective phases are obtained by a deviation calculator 2. The obtained deviations are multiplied by a given gain K by a multiplier 3. Voltage instruction values of (u), (v) and (w) phases which are obtained by voltage output converters 4 in accordance with the multiplication results are outputted to a PWM circuit 5.
