RELIABILITY-BASED OPTIMAL DESIGN FOR VIBRATION CONTROL OF STRUCTURES WITH UNCERTAIN-BUT-BOUNDED PARAMETERS
As an effective method, linear-quadratic regulator (LQR) has been widely used in vibration control of structural and mechanical systems.The issue of optimal vibration control of uncertain structures using LQR approach is studied from the viewpoint of reliability.A robust reliability method, where the bounded uncertain parameters are represented by interval variables, for LQR-based robust vibration control of uncertain structures is presented.The optimal vibration controller design of uncertain structures is carried out by solving an optimization problem with the objective of minimizing a quadratic performance index and subjected to robust reliability.The presented method provides a possible alternative for the harmonization and balance between robustness and performance requirements in controller design of uncertain structures.It is demonstrated via a practical structural control that the presented method is effective and feasible.
