Abstract
En 中文
We present formulas for the construction of optimal H-infinity, controllers that can be implemented in a numerically robust way. We base the formulas on the gamma-iteration developed in Benner, Byers, Mehrmann, and Xu (2007). The controller formulas proposed here avoid the solution of algebraic Riccati equations with their problematic matrix inverses and matrix products. They are also applicable in the neighborhood of the optimal gamma, where the classical formulas may call for the inverse of singular or ill-conditioned matrices. The advantages of the new formulas are demonstrated by several numerical examples. (C) 2011 Elsevier Ltd. All rights reserved.
