In this paper, we apply a multiple controller based adaptive method to solve a tracking problem, where the plant output is required to track a reference input. The proposed methodology is based on an unfalsification approach. The method relies on a finite set of candidate–controllers; depending on the evolving plant data, it learns and selects an optimal controller from the candidate controller...

This paper presents results of an investigation on how supplemental viscous damping can be used to control excessive deformations in asymmetric-plan buildings. It is shown that symmetric distribution of supplemental damping devices in the building plan is not necessarily the best way to control excessive deformations in an asymmetric-plan building; a value of the damping eccentricity equal to t...

Objective of this paper is to present robust control strategies able to handle acceleration feedback. The robustness of the controller is investigated in respect to both stability and performance measures. The uncertainty set is chosen as a convex one with either real or complex structured uncertainty. H1 control is ®rstly used to comply with the stability requirements whereas a m synthesis app...

1. Introduction Expressions in Icon [7] are capable of generating sequences of results during the course of their evaluation. For this reason, expressions in Icon are often referred to as generators. The primary control mechanism that exploits generators is goal-directed evaluation [12], which provides control backtracking [8]. This paper describes additional control mechanisms that have been a...
