The controller includes first and second phase lead compensators configured to perform phase lead compensation of a feedback primary command pressure, a lead compensation on/off determination unit configured to determine to set on or off the phase lead compensation, and an advance amount filter unit configured to smooth a change of a gain according to on/off determination of the phase lead compensation when the phase lead compensation is on/off-switched.
