Aerial refueling systems have been widely used to extend the flying distance in the military. This paper addresses the vibration control problem for an aerial refueling system. The aerial refueling system is modeled as a distributed parameter system governed by hybrid PDE-ODEs. Two control laws applied on the tanker and the tip drogue, respectively, are designed cooperatively to: (i) regulate the...
The vibration regulation problem is addressed for a flexible wing of the micro aerial vehicle (MAV) in this article. The flapping wing is considered with the flexible feature. We model the flapping wing as a DPS (distributed parameter system). Thus, we use the PDEs (partial differential equations) to describe the wing bending and the wing twist. Boundary control force and twisting moment are proposed...
This paper presents the dynamic modeling and vibration control design of a floating wind turbine system. Two flexible mooring lines attached to a flexible wind turbine tower (taut-moored floating spar) are used to represent the dynamics of system. The wind turbine tower is modeled as an Euler-Bernoulli beam, and the mooring lines are modeled as two strings. The control laws are designed to suppress...
