摘要
THAAD拦截弹是世界上少数能够进行能量管理控制机动的防空导弹之一。针对THAAD拦截弹先进的能量管理控制机动,从动力学模型、控制机制、运动学模型等方面提出了一套完整的方案。建立了非线性、强耦合、时变参数的大侧滑角弹体动力学模型,利用基于微分几何理论的反馈线性化技术将其解耦线性化,并设计了控制器实现姿态角的控制;建立了基于螺旋坐标系的运动学模型,并投影到地面坐标系来描述THAAD拦截弹的运动;最后通过六自由度仿真证明了该方案能够实现能量管理控制机动。
THAAD interceptor is one of the few air defense missiles which can carry out energy management steering maneuver( EMSM). A complete scheme to describe EMSM of THAAD interceptor is given from dynamics model,steering mechanism and motion model. A nonlinear,strong coupling,parameter time-varying dynamical model is employed to describe the large side-slip angle flight. Feedback linearization technique based on differential geometry is used for the autopilot design. A helical coordinate system is established which is suitable to describe the spiral motion. Finally,the 6-Do F( Degree of Freedom)simulation results have verified the performance of the proposed approach.
