Title:
CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/014216
Kind Code:
A1
Abstract:
In a control unit (1), an actual current-detecting subsection (40) detects the actual current flowing in a solenoid valve (104), and a primary command-generating subsection (20) generates a primary command voltage value while feeding back a current command value according to the actual current, which has been filtered in a filter processing subsection (50) so as to remove the frequency of a dither command voltage value cycle. Meanwhile, a dither amplitude command value-calculating section (83) calculates a dither command voltage value for varying the voltage cyclically. A dither command-superimposing subsection (31) generates a secondary command voltage value in which a dither command voltage value has been superimposed on a primary command voltage value. A PWM signal-generating subsection (32) converts the secondary command voltage value to a PWM signal and an applied voltage-generating subsection (60) generates an applied voltage to be applied on the solenoid valve (104) using the PWM signal.
