Adaptive Control Algorithm for Steady Flight of Mars UAV with Four Rotors

Abstract

Mars exploration is a hot issue at present, and Mars aircraft will become a new tool in Mars exploring. Four-rotor aircraft will be a powerful method in Mars aircraft investigation, because of its simple structure, high reliability, besides, it can also hover in the air, take off and land repeatedly. This paper combines Mars atmospheric environment with influence of UAV flight control, and improve PID to make controller parameters adjust themselves to temperature, pressure and atmospheric density on Mars. The effectiveness of adaptive control algorithm has been checked by using MATLAB method, which make Mars UAV with four rotors fly stably.
