Summary:This paper investigates the issue of flight control of fixed-wing aircraft (FwA) in heavy payload airdrop tasks, where smooth control commands are considered for actuators. The case that heavy payloads are mounted out of the symmetry plane is taken into account for dynamic modeling of the FwA, where the dynamic model is split into different modes corresponding to various situations of mounted payloads. Considering the dramatic variations of mass and center of gravity, a multi-equilibria switched system (MESS) is formulated for flight control, where the stable (unstable) modes correspond to the cases of symmetry (unsymmetry) mounting to ensure that the airdrop is with small rolling/yawing angles. By inserting the smooth portion, a smooth switched controller and the corresponding dwell time condition is obtained for MESS to tackle the flight control problem in heavy payload airdrop of FwA, which has not been considered before. The effectiveness and advantages of the proposed controller are demonstrated via simulations.
