Sliding Mode Tracking and Input Shaped Vibration Control of Flexible Hypersonic Vehicles

摘要：

　　The combined sliding mode controller-observer equipped with the input shaper is designed and analyzed for the longitudinal dynamics of flexible hypersonic vehicles(FHVs).First,the input–output linearization is employed to decouple the velocity and altitude dynamics.Then,the sliding mode controller(SMD)with modified exponential approach law(MEAL)is designed,which can render the closed-loop system track the commands effectively.In order to estimate the states that are not available for measurement,a nonlinear sliding mode observer is proposed.Moreover,by applying the input shaping(IS)technique,flexible dynamics with less elastic deformation and vibration can be obtained without destroying the closed-loop performance.Simulation results verify the effectiveness of the proposed control scheme.
