The problem of designing a flight control system for the tracking of parabolic trajectories to guarantee microgravity conditions within the aircraft cabin is considered. The proposed control action consists of two parts. The first one is a feedforward control guaranteeing good tracking of the desired parabola in the absence of environmental disturbances. The second part is a gain-scheduled output feedback to counteract possible misalignments between the desired output trajectory and the actual one. An estimation of the maximum output displacement in the presence of uncertainties and disturbances (wind gusts) is carried out. Simulation results are provided for a remotely piloted vehicle.

Abstract
The problem of designing a flight control system for the tracking of parabolic trajectories to guarantee microgravity conditions within the aircraft cabin is considered. The proposed control action consists of two parts. The first one is a feedforward control guaranteeing good tracking of the desired parabola in the absence of environmental disturbances. The second part is a gain-scheduled output feedback to counteract possible misalignments between the desired output trajectory and the actual one. An estimation of the maximum output displacement in the presence of uncertainties and disturbances (wind gusts) is carried out. Simulation results are provided for a remotely piloted vehicle.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
