Shape control of flexible structures


This research was performed by Saki Hakim, a Ph.D. student at the School of Mechanical Engineering at Tel Aviv University under the supervision of Moshe Fuchs. The general purpose of the research was to find optimal locations for sensors and actuators in flexible truss structures in order to maintain its original shape at the controlled degrees of freedom. It is assumed that the structure is subjected to a parametric family of disturbances (perturbations), such as temperature fields for space structures, traveling loads and so on. The novel idea was to design the best sensor and actuator locations without specifying a priori the value of the disturbance parameters. Although the perturbations cannot be characterized, the distortions caused by the perturbations have definite characteristics which can be studied and which form the basis for placing actuators and sensors.
