【Abstract】 To meet the development of aircraft actuating systems in the future, a novel air borne electro-hydrostatic actuator (EHA) which is integrated for power-by-wir e ( PBW) is designed. The paper describes the principle of work and features of EHA, models its components and the system, and simulates it with Matlab/Simulink. Th e EHA closed-loop system’s simulation obtained the perfect dynamic performances ; verify the correctness of the design with its control strategy. It will be use d as a part of airborne PBW actuating system.更多还原
