A NUMERICAL APPROACH TO ROBUST VIBRATION CONTROL OF A BASE-ISOLATED BUILDING USING WAVELETS
Hamid Reza Karimi and Ningsu Luo
|
Abstract:
In this paper, we study a method of finding an optimal control based on wavelet functions for vibration reduction of a base-isolated building subjected to actual earthquakes. The objective is two folds: (1) to find a computational method using properties of Haar functions, and (2) to calculate controller gains approximately by solving only algebraic equations instead of solving the Riccati differential. Simulation results are included to demonstrate the validity and applicability of the technique. |
