Finite-Time Adaptive Quantized Control for Quadrotor Aerial Vehicle with Full States Constraints and Validation on QDrone Experimental Platform

Drones
The issue of finite-time stability has garnered significant attention in the control systems of quadrotor aerial vehicles. However, existing techniques for achieving finite-time control often fail to consider the system’s state constraint characteristics

Tracking Control Design for Quadrotor Unmanned Aerial Vehicle

Defence Science Journal, 2017
The model of a quadrotor unmanned aerial vehicle (UAV) is nonlinear and dynamically unstable. A flight controller design is proposed on the basis of Lyapunov stability theory which guarantees that all the states remain and reach on the sliding surfaces.

Trajectory Planning and Replanning Strategies Applied to a Quadrotor Unmanned Aerial Vehicle [PDF]

Journal of Guidance, Control, and Dynamics, 2012
This paper considers the problem of trajectory planning/re-planning for a quadrotor unmanned aerial vehicle (UAV) system. In the fault-free case, the objective is to find the profile of the trajectory to follow so that the system constraints are not violated.
