摘要:
针对倾转旋翼机的最优过渡问题,采用动态最优控制来减小过渡时间、姿态角变化以及缓解驾驶员工作负荷。在飞行动力学模型的基础上引入操纵方程,通过引入操纵量方程来缓解操纵量的跳变;随后将飞行器的最优动态倾转过渡过程转变成非线性动态最优控制问题,引入合理的性能指标,基于序列二次规划算法进行求解;最终以 XV-15 为例,分析系统各个通道抗风扰能力以及进行全航线飞行仿真。实验结果表明,所设计的过渡段最优控制在倾转旋翼机的各个通道抗风扰性能突出,系统鲁棒性较好,具有较好的实际应用价值。
Abstract:
Aiming at the optimal transition problem of tiltrotor aircraft , this paper adopts dynamic optimal control to reduce transition time , attitude angle changes and alleviate pilot workload.In this paper , the control equation is introduced on the basis of flight dynamics model , and the jump of control quantity is alleviated by introducing the control quantity equation.Then , the optimal dynamic tilt transition process of the aircraft is transformed into a nonlinear dynamic optimal control problem , and a reasonable performance index is introduced to solve the problem based on the sequential quadratic programming algorithm.Finally , taking XV-15 as an example , the anti wind disturbance capability of each channel of the system is analyzed and the flight simulation of the whole route is carried out.The experimental results show that the optimal control of the transition section designed in this paper has outstanding anti-wind disturbance performance in each channel of the tilt-rotor aircraft , and the system has good robust performance , which has good practical application value.
