Abstract

PURPOSE: To obtain an aimed current pattern by detecting an applied voltage without detecting a current which lags greatly in terms of time, by controlling the load applied voltage so that the output of an arithmetic unit will be equal to that of a detector for the load applied voltage.
CONSTITUTION: This controller consists of unit 13 detecting a load applied voltage, unit 4 detecting a load current value, unit 7 setting the load applied voltage, coefficient unit 11 calculating the product of the output of unit 4 and resistance value R of inductive load 3, arithmetic unit 15 which adds or subtracts the output of coefficient unit 11 to or from that of unit 7, etc. Then, the load applied voltage is so controlled 7 so that the output of unit 15 will be equal to that of unit 13. Consequently, an aimed current pattern can be obtained by detecting the applied voltage without detecting a current lagging greatly in terms of time.
