摘要: 以远程制导炮弹为研究对象,针对传统导引与控制系统分开设计,在打击机动目标时容易脱靶的缺陷,提出一种2阶滑模导引控制一体化设计方法。将舵控伺服系统视为1阶动力学过程,考虑制导炮弹末制导过程的特点,采用小扰动假设,基于初始弹目视线建立了适用于制导炮弹的纵向平面内的导引控制一体化设计线性模型。在目标机动策略未知及制导炮弹气动参数有误差的情况下,以零化弹目视线角速率为准则,基于准连续滑模控制方法,设计了一种2阶滑模一体化导引控制律。为了体现一体化设计的优势,基于传统滑模控制理论,给出了一种独立的鲁棒自动驾驶仪与鲁棒导引律。仿真结果表明,存在有界不确定性的情况下,一体化导引控制律具有更高的命中精度。

Abstract: A 2-order sliding mode(2-SM) controller is proposed for an integrated guidance and control (IGC) design of extended range guided projectiles (ERGP). The canard loop is modeled as first-order dynamics. Considering the characteristics of ERGP, a linear model for IGC design is established based on the initial line-of-sight(LOS) with the assumption of a small disturbance. Then the linearized longitudinal integrated dynamics is formulated, in which the discrepancies from the target maneuver and the aerodynamic parameters are included. The quasi-continuous sliding mode control algorithm is adopted for a 2-SM IGC design for regulating the LOS rate to zero in finite time. To demonstrate the benefits of IGC, a separated robust autopilot and guidance law are also presented via the conventional SM control theory. Simulated results show that the proposed IGC controller is superior in that the miss distance is reduced.
