In order to research the influence of aviation hydraulic oil temperature change on the control performance of civil aircraft actuation system, a high-performance model is established by using Matlab for simulation analysis. Through the oil temperature-parameters controller, the influence of bulk modulus, density, viscosity on the system step response can be obtained. When the actuator in the active-disconnect state, the system gain can be simulated in different temperatures, and the frequency response performance correspond to the requirement.
