摘要:
根据优化控制和不变集理论,论述了飞行安全边界集及其计算方法。考虑受控制约束的情况,对系统进行增广,利用水平集算法,对某客机纵向含舵机特性的增广系统的飞行安全边界集进行了计算。利用计算结果,构建了飞行边界保护控制器,并对控制效果进行了仿真验证。结果表明,控制器能有效保护飞机飞行在不变集定义的安全边界内,且不影响正常的飞行控制。

Abstract:
According to optimal control and invariant set theory,we discussed the flight safe set and its calculation method. Considering constraints,we augmented the system. Using the level set method, the flight safe sets of the plane containing the longitudinal characteristics augmented system were calculated. Using the results to build a fly-ing border protection controller, we verified the control results of the simulation. The results and their analysis show preliminarily that the controller can effectively protect aircraft flying at a safe set definition within secure borders, without affecting on the normal flight control.
Key words:    invariant set    safe set    flight envolopes    Hamilton-Jacobi PDE
