摘要

This paper presents new methodologies to design a set of controllers such that every controller in the set preserves closed-loop stability of a given multivariable plant under prescribed loop failures. The proposed approaches differ from existing techniques in two ways: First, our methods are strictly based on frequency response data of the plant that can be easily measured by experiments. No mathematical models or system identification processes are used. Second, while most control design methods find one controller, we design a set of controllers satisfying the control objective. Two approaches are presented with examples illustrating the respective advantages.
