The Attitude Control Design of Air Defense Missile Based on Stochastic Robustness and Dynamic Inversion Control

在防空导弹姿态控制的优化中,针对具有匹配不确定性的远程防空导弹倾斜转弯非线性姿态控制问题,为提高系统性能,提出一种具有工程实用价值的随机鲁棒动态逆控制方法。在对导弹非线性控制模型进行精确线性化的基础上设计了动态逆控制器,综合权衡系统鲁棒稳定性和鲁棒性能指标设计要求,建立了面向工程设计的随机鲁棒代价函数,采用蚁群优化算法对控制参数进行优化。结果表明所设计的控制器在模型参数摄动时仍具有较强的鲁棒性。上述方法可为防空导弹姿态控制设计提供科学依据。

Concerning the air defense missile nonlinear BTF attitude control problem with matched uncertainties, a stochastic robust dynamic inversion control method with practical engineering value is proposed. The missile nonlinear control model is accurately linearized and a nonlinear dynamic inversion controller is designed. A cost function-oriented engineering of stochastic robust performance has been established by comprehensive considering the robust sta- bility and the robust performance of the controller performance specification. The ant colony optimization algorithm is adopted to optimize the control parameters. The simulation show that the controller has good robust performance while the control model exist parameter uncertainties, thus this method can provide a scientific basis for the air defense missile attitude control design.
