<P>PROBLEM TO BE SOLVED: To provide an electrification control apparatus of a solenoid capable of appropriately controlling current to be electrified to the solenoid even when there is variation in characteristics of the solenoid. <P>SOLUTION: An electrification control apparatus 100 of a solenoid includes: an integral operation part 13 which performs integral compensation of a deviation between target current Ir which is a target value of driving current to be electrified to the solenoid and detection current Ifb which is a detection value of actual driving current; a state quantity estimation part 14 which estimates state quantity of the solenoid on the basis of the detection current Ifb and indication voltage Vr to be supplied to a PWM control part 18 which controls electrification to the solenoid; and an indication voltage operation part 16 which calculates indication voltage on the basis of the deviation to which the integral compensation is performed by the integral operation part 13, the state quantity of the solenoid, and characteristic parameters showing characteristic variation for each of an inductance portion and a resistance portion of the solenoid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
