Abstract

Considering the impact of parametric uncertainties on Hypersonic Vehicle steady tracking control, a control approach based on integral sliding mode was proposed. First of all, linearized model of the Hypersonic Vehicle´s longitudinal dynamics with uncertainties was obtained based on small disturbance linearization method with chosen trim point. Then, an integral sliding mode surface that guaranteed the global robustness of the control system was selected based on the uncertainties model. Next, sliding mode control law was designed and stability was analyzed based on the Lyapunov theory. At last, a simulation platform was built and results showed the effectiveness of the control approach through Monte-Carlo simulation.
