Abstract

This paper focuses on quadratic performance analysis and output feedback gain-scheduling synthesis for parameter-dependent systems with
linear fractional representations (LFRs). New quadratic H2 and L2 performance analysis results based on full-block multipliers are given. A
novel gain-scheduling output feedback synthesis, which can be regarded as a natural extension of the loop shaping design procedure of McFarlane
and Glover to parameter-dependent systems, is proposed. This gain-scheduling technique is computationally attractive and yields a simple and
transparent control structure that can be easily implemented. Its effectiveness is illustrated on a benchmark missile autopilot example.
