摘要
为使拦截弹拦截高速机动目标时,具有快速产生较大过载的能力,提出一种直接力/气动力复合控制方法。该方法采用大姿控力矩,能够快速建立拦截弹的攻角。理论计算了引入直接力提升导弹过载响应性能的能力,对比分析了纯气动力控制和直/气复合控制过载响应能力,仿真结果表明,采用纯气动力控制很难大幅提升系统过载响应速度,而利用大姿控力矩直/气复合控制,系统过载响应速度能够显著提升,使控制效果达到最优。
To make missiles have the ability to generate large overloads quickly when intercepting the high speed maneuvering targets,presents a dual control method of lateral thrust and aerodynamic force.This method can rapidly establish the angle of attack of missiles through a large attitude control moment.The influence of lateral thrust on overload response capability of missile is calculated using theoretical methods. The overload response capability of aerodynamic control and dual control is compared and analyzed. Simulation results show that it’ s difficult to improve the response speed of the system by aerodynamic control. The overload response speed of the system can be improved significantly using the dual control of large attitude control moment,so as to achieve the optimal control effect.
