Structural Vibration Control using Observers

In this study, optimal control techniques using observers are applied to vibration control of a five story building model subjected to random excitation. The minimal order observer and the full order observer are adapted to estimate state variables of the controlled model. The optimal closed-loop control scheme using the observer is employed to the system. As numerical examples, we confirm efficiency of vibration control using the minimal order observer for the five-degree-of-freedom system modeled as the building model
