Research on Performances of Hybrid Actuation System with Dissimilar Redundancies
Hybrid actuation system (HAS) with dissimilar redundancies conforms to the development trend of future actuation systems in more electric aircraft (MEA).Hybrid Actuation system is composed of a traditional servo valve controlled hydraulic actuator (SHA) and an electro-hydraulic actuator (EHA).It has two operating models,active/passive mode (A/P) and active/active mode (A/A).In A/A model both actuators are actively controlled.Corresponding to A/A model,SHA is actively controlled and EHA is passively controlled in A/P model.The hybrid actuation system is built in the AMESim simulation environment,comparative analysis is performed when system operates in these two modes,such as signal response and force fighting.The simulation results provide a guideline to determine the specific operating mode of the system in different circumstances.
