Application of H Infinity Method to Modern Fighter Configuration

Abstract

H-Infinity optimal control theory, based on singular value loop shaping, is used to synthesize a controller for the statically unstable longitudinal dynamics of X-29 aircraft. Two design cases are studied: 2-input 2- output; and 3-input 3-output cases. H-Infinity theory provides a direct, effective procedure for synthesizing control laws satisfying specified performance objectives and robustness specifications. The 2 I/O case has better performance, a better response and is more robust, than 3 I/O case. Keywords: Control theory, Robust control systems, Sensitivity, Fighter aircraft, Configurations, Theses.
