Static Output Polynomial Control for Linear Structures

Abstract

Optimal polynomial controllers have been proposed recently for applications to active/hybrid control of seismically excited structures. Such controllers have been demonstrated to be effective in limiting the peak dynamic response of structures. In this technical note, a static output feedback polynomial controller is proposed. The static output polynomial controller uses only the information measured from a limited number of sensors installed at strategic locations, without an observer, thus facilitating practical applications of active/hybrid control systems to civil engineering structures. Advantages of the proposed static output controller, in terms of the load-adaptive capability for limiting the peak response of the structure and required control energies, are demonstrated by simulation results.
