Abstract: |
A new integrated guidance and control law was proposed based on continue predictive control, which exploit the inherent time scale separation existing in the missile dynamic between rotational and translational motions The missile states were predicted by appropriate expansions in a reasonable time span to capture the actual missile physics The optimal receding horizon control law was obtained through minimizing the predicted errors in the actual response, the desired response and current control expenditure The influence of control law parameters was also analyzed Simulations results show the effectiveness and accuracy of the proposed integrated design scheme. |
