โฆ Synopsis
Gain scheduling has proven to be a successful design methodology in many engineering applications. However in the absence of a sound theoretical analysis, these designs come with no guarantees on the robustness, performance, or even nominal stability of the overall gain scheduled design.
This paper presents such an analysis for one type of gain scheduled system, namely, a linear parameter-varying plant scheduling on its exogenous parameters. Conditions are given which guarantee that the stability, robustness, and performance properties of the fixed operating point designs carry over to the global gain scheduled design. These conditions confirm and formalize popular notions regarding gain scheduled design, such as the scheduling variable should "vary slowly.

A characterization of gain scheduled controllers satisfying appropriate requirements is presented, and an implementation is suggested. The results are illustrated by several examples of the analysis and implementation of gain scheduled controllers.
A family of linear, continuous-time plants parametrized by a vector of unknown parameters taking values in a known finite set is considered. The problem investigated consists in finding a linear discrete-time compensator that, independently of the actual value of the parameter vector, guarantees zer
