In this paper, the trajectory tracking problem of the position and yaw angle of an underactuated quadrotor UAV is studied. Considering that the quadrotor UAV often encounters unknown disturbance resulted by model parameter perturbations and environmental changes, a new L2‐gain robust control method is presented based on dissipation theory. First, the dynamic model of the quadrotor UAV with disturbances...
A viable and affordable real-time and online control technology named remote production dashboard (RPD) for discrete manufacturing process based on knowledge service is proposed. Firstly, the basic framework of RPD consisted of production environment layer, data process layer, knowledge service layer and man-machine interaction layer is constructed. Secondly, the principles of two key technologies...
