Linear parameter varying controllers for the ADMIRE Aircraft longitudinal dynamics

This paper details the design of various Linear Parametrically Varying (LPV) controllers for the ADMIRE fighter aircraft benchmark model. Attention is focused on the improvement of the ADMIRE longitudinal dynamics handling qualities. In this benchmark, performance and robustness must be guaranteed over an extensive portion of the flight envelope. To this end, three robust LPV gain-scheduling control design techniques are investigated. Each technique is assessed in terms of conservatism, off-line computation cost and ease of implementation. For each controller, the non-linear aircraft responses are given and discussed.
