突防导弹机动、制导与控制一体化设计

为提高导弹的突防能力,提出了一种机动、制导与控制一体化设计的方法。根据运动跟踪变结构控制理论设计了机动与导引协调的制导律。对于导弹飞行过程中存在的强耦合、快时变以及气动参数摄动引起的不确定性等问题,采用自抗扰控制技术设计制导与控制一体化系统。研究结果表明:设计的一体化系统解除了传统制导律对导弹机动性能的约束,显著地提高了导弹的机动灵活性和弹道的复杂程度;一体化控制系统具有良好的动态特性和很强的鲁棒性,能够适应复杂战场环境下的突防需求。

Integrated design of maneuver,guidance and control for penetration missile

An integrated design method of maneuver, guidance and control for improving the penetration capability of the missile is proposed. A maneuvering and guidance coordination guidance law is designed based on the motion tracking variable structure control theory. To solve the problems such as strong coupling, fast time-varying and uncertainties caused by perturbation of aerodynamic parameters during missile flight, the guidance and control integration system is designed by using the active disturbance rejection control technique. The simulation results indicated that the integrated system eliminates the constraints of the traditional guidance law on missile maneuverability, which significantly improves the missile maneuverability and complexity of the ballistic; The integrated control system has good dynamic characteristics and strong robustness, which can meet the requirements of penetration in the complex battlefield environment.
