Abstract

The number of EMA (Electro-mechanical actuator)-based UAVs (unmanned air vehicle) are on the rise. The EMAs are generally applied to UAV as primary and secondary flight control surfaces actuator, speed or air brake actuator, door actuator, landing gears and so on. Since all EMAs are expressed as 2nd- or 3rd-order simplified mathematical models in M&S (modeling and simulation) phase, dynamic estimation of the EMAs power consumption is almost impossible and it causes battery/generator sizing problems in the design phase. Especially for UAVs that have all EMAs for the primary and secondary flight control actuators, electric power consumption is increased in flight because of hinge moments of the control surfaces caused by air pressure during flight. In this thesis, we provide a method for dynamic power consumption estimation of the primary and secondary control surface EMAs for M&S through the electro-mechanical dynamics and aerodynamics. Not only simulation results but also successful flight test results are presented in this work.
