  • A dynamic model of electric-hydraulic loading system was established based on the principle analysis of electro-hydraulic load simulator, which was applied to the earth-experiment of hydraulic assistor for the helicopter pitch adjusting. Controllers designed by conventional control theory were not effectual because of the uncertain factors such as difficulties in access to precise structure parameters of electric-hydraulic loading system and nonlinearity of loading flux in servo valve. Therefore the robust control strategy of electric-hydraulic loading system based on H theory was investigated in this work. Through choosing suitable weight functions and using the designing method of mixed sensitivity, the robust controller was solved by the linear matrix inequality (LMI) algorithm. The experiment results prove the high efficiency and superiority of the robust force controller which is presented by this work.
