Robust Coordinated Longitudinal Control of MAV Based on Energy State

Fixed-wing Miniature Air Vehicle (MAV) is not only coupled with longitudinal motion, but also more susceptible to wind disturbance due its lighter weight, which brings challenges altitude and airspeed controller design. Therefore, in this paper, an improved control strategy based on energy state, proposed address the above-mentioned issues. The utilizes Linear Extended State Observer (LESO) observe states of MAV, then designs a Multiple-Input Multiple-Output (MIMO) coordinated Total Energy Control (TEC) MAV. performance has been successfully verified Model-in-the-Loop (MIL) simulation Simulink, comparative test classical TEC algorithm carried out.
