Abstract
In this paper, the problem of thermally induced vibration suppression in a
thermoelastic beam is studied. Physical equivalent of the present problem is
that a thermoelastic beam is suddenly entering into daylight zone and
vibrations are induced due to heating on the upper surface of the beam or
thermoelastic beam in a spacecraft enters to intensive sunlight area just
after leaving a shadow of a planet. Thermally induced vibrations are
suppressed by means of minimum using of control forces to be applied to
dynamic space actuators. Objective functional of the problem is chosen as a
modified quadratical functional of the kinetic energy of the thermoelastic
beam. Necessary optimality condition to be satisfied by an optimal control
force is derived in the form of maximum principle, which converts the
optimal vibration suppression problem to solving a system of distributed
parameters system linked by initial-boundary-terminal conditions. Solution
of the system is achieved via MATLAB? and simulated results reveal that
thermally induced vibration suppression by means of dynamic space actuators
are very effective and robust.
