© 2015 American Automatic Control Council. This paper presents a numerically attractive approach to design reduced-order multi-objective H2/H∞ controllers for discrete-time linear parameter-varying (LPV) systems. The proposed controller synthesis approach relies on an a priori computed polynomially parameter-dependent full-order LPV controller that stabilizes the LPV system for all possible parameter trajectories. This full-order controller is subsequently used in a sufficient linear matrix inequality (LMI) optimization problem for reduced-order H2/H∞ LPV synthesis. Pólya relaxations are used to obtain tractable LMI formulations, and a simplicial subdivision of the parameter domain is applied to relieve the numerical burden. Experimental validations on a lab-scale overhead crane with varying cable length illustrate the practical viability of the approach. ispartof: pages:125-130 ispartof: Proceedings of the 2015 American Control Conference vol:2015-July pages:125-130 ispartof: ACC location:Chicago, IL, USA date:1 Jul - 3 Jul 2015 status: published |
