研究了寻的导弹的导引控制一体化设计问题.建立了俯仰通道的一体化导引与控制系统模型,并利用非线性状态变换将模型转化为标准形式;为处理系统中存在的非匹配未知有界不确定性,采用滑模控制方法设计了自适应的非线性一体化导引与控制律,该反馈控制律不但可以保证导弹精确命中目标,而且能保证导弹自身姿态的稳定性.导弹的六自由度非线性数值仿真结果验证了所提的导引控制一体化设计策略的正确性和可行性.

The problem of integrated guidance and control for homing missiles was investigated. The integrated guidance and control model of the pitch plane was established,and further changed into the normal form by nonlinear coordinate transformation;in order to deal with the unmatched and unknown bounded uncertainty,an adaptive,nonlinear integrated guidance and control law was designed by adopting sliding-mode approach,to ensure the accuracy of target interception and the stability of the missile dynamics. The 6DOF nonlinear missile simulation results demonstrate the correctness and feasibility of the proposed integrated guidance and control design strategy.
