Aircraft Hydraulic Booster and Rudder System Modeling and Performance Simulation

A simulation model for analyzing a hydraulic booster and rudder system was established based on a typical hydraulic booster of a certain type of aircraft flight control system. The system model that consisted of the dynamics of load, piston, cylinder, and spool of the valve was derived by considering the influences of nonlinear factors such as oil stiffness, structure stiffness, friction and leakage. The influences of key parameters on the system performance and stability were analyzed and elaborated by focusing on the system stability and static dynamic characteristics. The simulation results show that this system has good stability and quick response, as well as good performance in both of static and dynamic.
