PURPOSE: A resonance suppression control technique of precision position servo flight control actuator system is provided to facilitate the selection of a controller variable by applying a dynamic pressure feedback control technique. CONSTITUTION: A resonance suppression control technique of precision position servo flight control actuator system is as follows. The pressure of a cylinder expansion compartment and that of a cylinder contraction compartment in a servo actuator(2) are measured. The pressure(15) of the cylinder expansion compartment and the pressure(16) of the cylinder contraction compartment are delivered to an adder and a pressure difference signal is generated. The pressure difference signal is delivered to a high pass filter(17). A pressure difference signal having a band lower than the corner frequency of the high pass filter is attenuated. A pressure difference signal having a band higher than the corner frequency of the high pass filter passes through the high pass filter and is multiplied by a dynamic pressure feedback controller gain value(18) to generate a dynamic pressure feedback control signal. The dynamic pressure feedback control signal is offset by a position error signal and the size of the synthesized error signal delivered to a servo amp(12) diminishes. The operation of a servo actuator is suppressed.
