H„ 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„ 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 faster response and is more robust, than the 3 I/O case.
Discussion and comparison of results are given.
