Control of hypersonic vehicles in cruise and glide periods

This paper proposes a controller for the hypersonic vehicle in cruise period and one in glide period in order to make the hypersonic vehicles achieve and maintain desirable flight characteristics. Both of the controllers are based on a control-oriented model of the longitudinal dynamics and the PIF-LQR algorithm which is easily implemented in the engineering are applied. Numerical simulations are proposed to verify the effectiveness of the two proposed controllers.
