摘要
针对无人作战飞机末端攻击制导控制一体化设计问题进行研究。建立一体化制导与控制系统模型,在此基础上采用轨迹线性化控制方法设计一体化控制律,为处理系统中存在的气动参数摄动、测量误差干扰和目标机动等大量不确定性,采用非线性干扰观测器技术对不确定性进行估计并加以补偿,并基于Lyapunov原理证明所设计方法的稳定性。仿真结果表明:所设计的制导控制一体化方法有效地提高控制精度,并保证良好的鲁棒性。
The integrated guidance and control（IGC） design for unmanned combat aircrafts terminal attack was investigated. The IGC system model was established, and an IGC law was designed by the trajectory linearization control（TLC） method. In order to deal with high uncertainties, such as aerodynamic parameter perturbation, measurement error interference, target maneuver, and so on, a nonlinear disturbance observer（NDO） was employed to estimate and compensate for the uncertainties. By using the Lyapunov theorem, the stability of the designed method was proved. Simulation results demonstrate the superiority and effectiveness of the designed IGC method in the aspects of guidance accuracy and system robustness.
