基于滑模控制的飞行器螺旋机动、制导与控制一体化设计研究

针对空舰飞行器末制导过程中突防能力不强；制导、控制回路分离设计在带宽分离假设条件不满足情况下的控制效果较差的两方面问题，将飞行器制导与控制回路进行一体化设计，并引入三维螺旋机动的弹道机动形式，实现了螺旋机动、制导、控制一体化的设计研究. 首先对飞行末段的制导、控制回路进行了一体化建模，之后应用滑模控制方法，完成了制导与控制一体化的控制律设计，而后引入了对视线倾角速率与视线偏角速率的周期性拉偏，完成了螺旋机动、制导、控制一体化设计，仿真结果表明，本文设计的控制律在保证对目标的精准打击能力的同时具备了攻击过程中的弹道螺旋机动能力. 

Research on Integrated Design of Aircraft Spiral Maneuver,Guid-ance and Control Based on Sliding Mode Control

To solve the problems of the capability deficiency of air-to-ship aircraft in the terminal guidance process and the inefficient control due to the separation of guidance and control loop design with unsatisfied assumption of bandwidth separation, an integrated design method was proposed for the guidance and control loop of the aircraft. Taking a ballistic maneuvering form with three-dimensional spiral maneuver, the design method was arranged to achieve spiral maneuvering, guidance and control integration. Firstly, an integrated model was established for the guidance and control loops at the end of the flight. And then, a sliding mode control method was applied to complete the control law design for guidance and control integration. Finally, introducing a period inclination rate of the line of sight obliquity and the line of sight deflection rate, the integrated design was carried out for spiral maneuvering, guidance and control integration. The simulation results show that the control law designed in this paper can improve the strike accuracy and provide a ballistic spiral maneuverability in the attack process.
