Shape control of large scale flexible structures. (1st report. Modeling and static repeating shape control in a one dimensional model).

Shape Control in Implicit Modeling

Recently, implicit patches have emerged as alternative modeling primitives for three dimensional objects. In designing three dimensional models, one often encounters various shape requests. This paper develops techniques for satisfying such requests through shape control. In particular, we show how to achieve the convexity of quadric patches or cubic patches.

Design of Surface Shape Control for Large Two-Dimensional Array

This paper develops design technology for active shape control of reflective surfaces using large spatially distributed sensor/actuator arrays. The classically-motivated design methodology achieves scalability to very large array sizes by imposing spatially localized fixed-form constraints on the control law structure. Linear program is solved to find parameters of this structure. The design is...

Static Shape Control for Adaptive Wings

A theoretical method was developed, and experimentally validated, to control the static shape of flexible structures by employing internal translational actuators. A finite element model of the structure, without the actuators present, is employed to obtain the multiple-input, multiple-output control-system gain matrices for actuator-load control as well as actuator-displacement control. The me...
