摘　　要：针对末制导律的优化设计问题,为提高导弹的制导精度和攻击能力,提出了一种新的一体化制导控制系统设计思路,首先在拦截平面内给出一体化制导控制系统的数学模型;利用状态重定义后的一体化数学模型,用反演控制理论和高阶滑模观测器技术,设计了一体化制导律,并给出制导律的稳定性分析,并对传统制导控制系统的比例导引律、PID控制律和一体化制导律分别进行仿真验证,仿真结果表明一体化制导律能有效克服目标机动和自动驾驶仪延迟带来的制导误差,制导性能更优。To improve the terminal hitting performance, an integrated guidance and control method was proposed based on the back-stepping control theory and the higher order sliding mode control theory. The integrated guidance and control system was firstly modeled in the intercepting planar during the terminal guidance. The integrated guid- ance and control law was then derived, and the stability of the proposed guidance law was analyzed based on Lya- punov theory. Numerical simulations were finally carried out to verify the correctness and effectiveness of the proposed guidance law. The simulation results show that the proposed guidance law performs better guidance indexes than the traditional methods.
