Abstract:

A reduced-order model for the design of guidance and control system of hypersonic vehicles in dive flight phase is developed, and a novel design approach of six-degree-of-freedom (6DoF) guidance and control system is proposed. The 3D coupling relative dynamics between the target and the hypersonic vehicle are derived based on accurate transitions of coordinate systems. An analytical model for components of acceleration of the hypersonic vehicle in the ballistic frame and the three-channel body rates is obtained. The 3D diving relative model, with the control surface fin deflections being the inputs, is denoted as the 6DoF integrated guidance and control design model. The system order and the tuning parameters of the 6DoF guidance and control system are reduced. The process of calculating the angle of attack and sideslip angle based on the desired overloads is omitted. In addition, the novel analytical model is applied to substitute the compensated dynamics for the traditional tracking processes of the rotational control loops. A novel design approach of 6DoF guidance and control system is proposed. The effectiveness and robustness of the proposed integrated guidance and control scheme are investigated and verified using an air-breathing generic hypersonic vehicle.
