Passivity-based output-feedback control of turbulent channel flow

Optimal feedback control of turbulent channel owBy

Feedback control equations have been developed and tested for computing wall-normal control velocities to control turbulent ow in a channel with the objective of reducing drag. The technique used is the minimization of a \cost functional" which is constructed to represent some balance of the drag integrated over the wall and the net control eeort. A distribution of wall velocities is found whic...

Passivity-based Dynamic Visual Feedback Control with a Movable Camera

This paper deals with the dynamic visual feedback control with a movable camera instead of a fixed camera in the fixed camera configuration. Firstly the brief summary of the visual feedback system with a fixed camera is given with the fundamental representation of a relative rigid body motion. Secondly we construct the new error system in order to consider the camera field of view. Next, we der...
