摘要
En 中文
Precision strike systems struggle to simultaneously achieve terminal impact angle and zero miss distance constraints. This is especially challenging with limited resources and uncertain autopilot dynamics. This paper proposes a guidance law utilizing a virtual coordinate system. Its adaptive parameters, derived from Lyapunov analysis, are guaranteed to be stable. The method introduces two key innovations. First, a virtual target transformation ensures compatibility with conventional guidance architectures by decoupling angular error compensation. Second, a nonlinear parameterization eliminates offline tuning, enhancing computational efficiency for resource-constrained systems. These advancements enable real-time adaptation to autopilot dynamics, ensuring robust performance. Rigorous Lyapunov-based stability analysis confirms the method's convergence under defined constraints. Comparative simulations validate its superiority over existing approaches, demonstrating an 87% success rate and a 42% reduction in total acceleration compared to Linear Impact Angle Constrained Guidance.
