Paper Abstract

In this paper, we show how to design decentralized controllers for smart structural systems to achieve multiple objectives associated with performances defined by H∞ or H2 norm, robust stability for model uncertainty, and limited actuator authority. The decentralized controller is designed in a sequential procedure for each control loop by solving synthesis conditions represented in terms of linear matrix inequalities (LMIs). The simultaneous design of decentralized controller, formulated as a non-convex minimization problem, is also discussed. The proposed design method was experimentally tested on a three-mass structure with three control loops.
