Abstract

This paper compares performance and robustness properties of full order linear quadratic Gaussian (LQG), MinMax, and central controllers as applied to a cantilevered Euler-Bernoulli beam. The numerical approximation of the beam is based on a Galerkin finite element scheme with cubic splines. The numerical results demonstrate that all three controllers offer comparable performance and robustness properties for this particular problem.
