Abstract

Control Oriented Models Minimum Redundancy Multidimensional Systems Multivariable Polynomials Parametric Variation Robust Control Uncertain Linear Systems
Robust control system analysis and design is based on an uncertainty description which separates the uncertain system from the nominal system. Low-order models of this structure are difficult to formulate for many practical problems involving uncertainty in the physical parameters of the system. This paper presents a matrix-based method of directly constructing a low-order uncertainty model for real parameter problems involving multivariate rational functions of the uncertain parameters.
