ABSTRACT

Triplex Redundant Hybrid Actuation System (TRHAS) with dissimilar redundancies conforms to the development trend of future actuation systems in more electric aircraft. It is composed of a traditional Servo Valve Controlled Hydraulic Actuator (SHA), an Electro-hydrostatic Actuator (EHA) and an Electro-mechanical Actuator (EMA). The structure and operating principle of TRHAS are represented and its linear mathematical model and simulation model in AMESim are established. The operating modes are simulated and analyzed preliminarily. Displacement response curves are given and the force fighting phenomenon is analyzed. All of these works lay the foundation for the future force equalization control.
