针对动能杀伤器独特的弹体特征,提出一种基于姿控和轨控发动机的气动力/直接力复合控制方案.该复合控制方案能有效利用弹体自身升力,使姿、轨控发动机协同作用,共同提供法向过载.建立了基于非线性干扰观测器的滑模反演控制方法,并进行了闭环控制回路的Lyapunov稳定性分析.最后对复合控制方案、非线性干扰观测器和滑模反演控制律进行了仿真实验,仿真结果表明了所提出的控制方案是可行而有效的.
Aiming at the unique projectile characteristics of kinetic energy killer, this paper proposes a compound control scheme of aerodynamic force / direct force based on attitude control and orbit controlled engine.The composite control scheme can make effective use of projectile own lift and make the attitude and rail control engines work together , And jointly provide normal overload. A sliding mode inversed control method based on nonlinear disturbance observer is established and the Lyapunov stability analysis of closed-loop control loop is carried out. Finally, the complex control scheme, nonlinear disturbance observer and sliding mode anti- The simulation results show that the proposed control scheme is feasible and effective.
