Control for Flexible Structures Subject to Random Disturbance

Multiobjective Optimization Criteria for Linear Structures Subject to Random Vibrations

A structural optimization criterion for linear mechanical systems subject to random vibrations is presented for supporting engineer’s design. It is based on a multiobjective approach whose Objective Function (OF) vector is done by stochastic reliability performance and structural cost indices. The first ones are structural reliabilities, and are evaluated for one or more failure types; they are...

Control of a deformable mirror subject to structural disturbance

Future space based deployable telescopes will be subject to non-atmospheric disturbances. Jitter and optical misalignment on a spacecraft can be caused by mechanical noise of the spacecraft, and settling after maneuvers. The introduction of optical misalignment and jitter can reduce the performance of an optical system resulting in pointing error and contributing to higher order aberrations. Ad...

A Slewing Control Experiment for Flexible Structures

A hardware setup has been developed to study slewing control for flexible structures including a steel beam and a solar panel. The linear optimal terminal control law is used to design active controllers that are implemented in an analog computer. The objective of this experiment is to demonstrate and verify the dynamics and optimal terminal control laws as applied to flexible structures for la...
