I N recentyears,unmanned aerialvehicles(UAVs)have been widely employed in different applications,both military and civilian.Especially,a fast growing civil UAV market is predicted over the next decades.However,most currently developed UAVs depend on simple control strategy.They require exact modeling of the UAVs'dynamics and are vulnerable to externaldisturbance.Therefore,there is great need for advanced control strategies that are robust to modeling uncertainties and disturbances.This special issue focuses primarily on the problem of control design for UAVs with high robustness.

In this special issue,fourteen papers have been selected to representcurrenttrends and advances in the advanced control of UAVs.The paper by Xia et al.describes the development of attitude control algorithm for multiple UAVs with modeling uncertainties and disturbances.Duan et al.discuss an optimization approach for multiple unmanned combat aerial vehicles based on particle swam method.Xian et al.explore an adaptive flight control design for a 6 degree-of-freedom unmanned helicopter under uncertain dynamics.The paper from Zhou et al.presents a robust tracking methodology for multiple UAVs.Zheng etal.provide a robuststate estimation approach for a quadrotor UAV with monocular camera and inertial measurement unit as the main onboard sensors.Mu et al.describe a nonlinear robust controller for an unmanned hypersonic vehicle by using continuous sliding mode method and disturbance observer.The paper by Peng et al.provides a robustadaptive controlalgorithm fora coaxialeightrotor UAV by combing sliding mode approach with radial basis function neural network.Wang et al.utilize disturbance observer to explore a robust tracking control for a vertical take-off and landing UAV which is subjected to external disturbances. Zha et al.construct a dynamic multi-team antagonistic games model for multiple UAVs with incomplete information.By using the operative scenario approach,Fang et al.present a probabilistic robust linear parameter-varying control methodology for a small unmanned helicopter.The paper by Zhang et al.provides an adaptive robust attitude control design for an unmanned hypersonic vehicle based on the backstepping approach.The paper by Liu etal.explores an attitude control design for UAV which can achieve finite time convergence. Miao et al.utilize onboard monocular video sensor to setup an autonomous control strategy in GPS-denied area.Liang et al.explore an decoupling trajectory tracking control design for an unmanned re-entry vehicle with high nonlinearity and strong coupling between the vehicle's states.

Together,these fourteen papers provide the state-of-the-art theoreticalanalysis and controldesign for UAVs,and highlight the research currently ongoing in this area.We would like to thank the authors,reviewers,and the editor-in-chief for their support to this special issue.We hope that you enjoy reading this issue and the papers!
