ABSTRACT

The dynamics of a scaled actively controlled model of a maneuverable aircraft in three degrees of freedom (3DOF) gimbals is considered. A robust control algorithm suppressing wing rock motion at high angles of attack is proposed. The robust control design is based on linear parameter varying design methods, which are an extension of H optimization on linear parameter-dependent systems. Wing rock suppression with the designed control law is validated using nonlinear time-domain simulations.
