Linear Quadratic Gaussian-Alpha Control with Relative Stability and Gain Parameter for the Structural Benchmark Problems
Publication: Journal of Engineering Mechanics
Volume 130, Issue 4
Abstract
This paper introduces a linear quadratic Gaussian (LQG)-α control with adjustable relative stability and gain parameter for the benchmark problems. The considered control algorithm is one active control methodology. It provides a various relative stability and introduces a gain parameter via a LQG design. The relative stability not only controls a guaranteed settling time for the system but also increases the controlled system robustness. The paper focuses on both wind- and earthquake-excited benchmark problems of the third generation. The simulation of this LQG-α control to these benchmark problems is provided. An additional simulation of the proposed control to a largely perturbed wind-excited benchmark problem is also provided. The control results, with respect to the evaluation criteria following the benchmark problems, are included for further comparison.
