直接力/气动力复合控制系统有限时间稳定机理及控制方法

The lateral thrust and aerodynamics blended control is the key technique for the guidance and control of the latest generation anti-missile weapon. The stability mechanism is the basis scientific issue of blended control. Because of the short working time for guidance control system under high hit speed and the existences of lateral jet interference, The finite time stability mechanism and robust control for blended control system become the key issues to be solved. Hence, this project will focus on the research of the impulsive differential control model and characteristics of impulsive control for blended control. The stability mechanism and finite time stabilization criterion, the stability robustness in the existence of lateral jets interference and robust finite time stabilization for blended control system will be investigated deeply. Theree key issues for blended control will be solved, that is the coupling influence between the discrete impulsive change and the dynamics of continuous aerodynamics control, the stabilization mechanism and finite time stabilization criterion, and the robust finite time stabilization with time-varying impulse constraints. Furthermore, the gereral conclusions for the interaction and collaborative control between the continuous aerodynamics control and the impulsive action will be given. Finally, the control design principles and the blended control quality for lateral thrust control and aerodynamics control will be deeply explored. These results of the project will provide theoretical support for research on guidance and control technologies for new generation air defense missile, and has important academic significance and a wide range of application..
