The flight of relatively stiff aircraft can be adequately controlled by standard means, i.e., by the engine throttles and control surfaces. When the flexibility becomes a factor, the standard controls may not be sufficient. In several earlier papers,

A variety of aerospace structures, such as missiles, spacecraft, aircraft, and helicopters, can be modeled as unrestrained flexible bodies. The state equations of motion of such systems tend to be quite involved. Because some of these formulations we

A new generation of aircraft, namely, unmanned aerial vehicles (UAVs), and, in particular, autonomous UAVs, are expected to carry out very critical maneuvers, well in excess of what pilots are able to tolerate. A newly developed theory for the dynami

This work is concerned with time simulations of the response of flying flexible aircraft to initial conditions and external excitations, such as gusts. The simulations are based on a unified formulation of the problem of dynamics and control of maneu

This work represents a new paradigm for the dynamics and control of maneuvering flexible aircraft. Using the system concept, the theory integrates seamlessly all the necessary material from the areas of analytical dynamics, structural dynamics, aerod

Building structures represent complex distributed-parameter systems. The motion of such systems is described by partial differential equations complemented by suitable boundary conditions. For control design purposes, distributed-parameter systems mu

A balanced presentation that encompasses both formalism and structure in analytical dynamics, this text also addresses solution methods. Its remarkably broad and comprehensive exploration of the subject employs an approach as natural as it is logical

This paper develops a general approach to the three-dimensional maneuver and vibration control of a robot in the form of a chain of flexible links. The equations for the rigid-body maneuvering motions are derived by means of Lagrange equations in ter

The objectives of control of structures in earthquakes are to prevent injury to occupants and damage to contents and to protect the integrity of the structure. Both objectives can be achieved through base isolation and feedback control, whereby the s

This paper is concerned with the ability of tanks partially filled with water to withstand earthquakes. The interest lies in rectangular water tanks, which have received little attention to date. The analysis is relatively involved and includes the d
