摘要
针对导弹末制导段的制导控制问题,基于自抗扰控制和反演终端滑模控制,提出了一种导弹制导控制一体化设计算法。利用块严格反馈系统描述一体化模型,将存在的模型误差、目标机动等看做未知干扰。采用扩张状态观测器对系统不确定性和干扰进行估计和补偿。设计反步终端滑模控制方法实现导弹的姿态控制。仿真证明了设计的一体化算法可以获得较小的脱靶量,系统对存在的内外干扰和不确定性具有较强的鲁棒性。
Based on active disturbance rejection control and the backstepping-sliding mode design method, an integrated guidance and control design is proposed for missiles during the terminal course.The integrated model is formulated as a block-strict-feedback nonlinear system,in which modeling errors and target maneuvers are viewed as unknown uncertainties.An extended state observer is developed to estimate and compensate the impact from uncertainties and disturbances.A backstepping-sliding mode controller is proposed to realize the at-titude control.Simulation results show that,with the application of the proposed method,small miss distances are achieved,and the system is robust against system uncertainties and disturbances.
