Abstract: The electrohydraulic load simulator is a kind of typical passive force servo system. The large extraneous force caused by strong disturbance of the rudder displacement affects the static and dynamic performances of loading system seriously. According to electrohydraulic servo load simulator, improved structure invariance compensation (ISIC) is presented to correct phasic lag of estimative velocity. Moreover, based on Fourier series, corrected velocity is extended to different frequency points and tracking control of multi-frequency signal is realised. The real loading experiment results indicate that ISIC control method could compensate extraneous force effectively.
