Abstract

We present a computational spectral factorization method to solve the optimal state feedback control problem for flexible structures with the following features:

1) Mathematically rigorous

2) Wide rangeof applicability

3) Flexibility of design

4) Fast and Efficient

5) Mini-computer (versus Super-computer) implementation. We apply this method to the following systems:

   1) A membrane

   2) A string

   3) An Euler-Bernoulli/Timoshenko beam models

   4) A Beam with structural damping and boundary control
