Autonomous landing is a challenging and important task for rotorcraft-based unmanned aerial vehicle (RUAV). This paper presents an autonomous landing algorithm for RUAV. The accurate landing is achieved by generating reference trajectory using near-minimum-time maneuver method and tracked with Lyapunov stabilizing approach. Along with this the testing environment for RUAV is developed to validate...
The safe landing of unmanned aerial vehicles (UAVs) under various wind conditions has been a challenging task for decades. We design an autolanding control system which consists of a throttle control subsystem and an altitude control subsystem based on the Active Disturbance Rejection Control (ADRC). In contrast to previous methods, our approach can directly and real-timely estimate the UAV's internal...
In this paper a nonlinear control has been designed using the dynamic inversion approach for automatic landing of unmanned aerial vehicles (UAVs), along with associated path planning. This is a difficult problem because of light weight of UAVs and strong coupling between longitudinal and lateral modes. The landing maneuver of the UAV is divided into approach, glideslope and flare. In the approach...
In this paper we focus on the problem of modeling and controlling a certain configuration of UAV (Unmanned Aerial Vehicle) considering explicitly the interaction with the environment. This innovative problem is particularly interesting in order to employ unmanned aircrafts in tasks and operations which may require explicitly or implicitly contacts between the UAV itself and the environment such as...
