Abstract

PURPOSE: To increase the accuracy of controlled position, by controlling the electrical quantity fed to the coil by comparing the position detection signal of moving iron core with the set signal.
CONSTITUTION: The position of the linking fixture 11 of the position control solenoid 12 is detected at the potentiometer 36, and it is fed to the differential unit 21 as the actual value Y30, the difference with the set value X29 is obtained and integrated, and it is fed to the adder 24 together with the set value X29 signal for addition. Further, the rectangular wave signal compared with the reference signal of sawtooth wave at the comparator 28 is fed to the power transistor 31 for switching operation, and the pulsive output signal 33 obtained is fed to the position control solenoid 12 to regulate the controlled position. Thus, since feedback control is enabled so that the unbalanced extent between the set value X and the actual value Y can be zeroed, the position control with reproducibility for the control object can be made.
