Adaptive Longitudinal Control of UAVs with Direct Lift Control
IFAC-PapersOnLine, 2016 Abstract In this paper, a nonlinear control technique based on Direct Lift Control (DLC) is proposed to control the longitudinal dynamics of unmanned aerial vehicles. The baseline controller is designed using a nonlinear dynamic inversion technique. As the effectiveness of the baseline controller depends on the knowledge of aircraft dynamic model and

On the Actuator Dynamics of Dynamic Control Allocation for a Small Fixed-Wing UAV With Direct Lift Control [PDF]
IEEE Transactions on Control Systems Technology, 2020 A novel dynamic control allocation method is proposed for a small fixed-wing unmanned aerial vehicle (UAV), whose flaps can be actuated as fast as other control surfaces, offering an extra way of changing the lift directly. The actuator dynamics of this kind of UAVs, which may be sluggish comparing with the UAV dynamics, should also be considered in ...

International Journal of Advanced Robotic Systems, 2018 This work proposes a novel development of sliding mode control (SMC) for quadrotor helicopters utilizing offset cancellation technique. Most of the works on sliding mode control for quadrotors assumed that all rotors were identical, but in fact, the ...
