具有终端约束的模糊导引律设计

本文研究了有终端约束的拦截任意机动目标的模糊导引律设计问题。应用模糊Ｔ－Ｓ线性模型，来逼近拦截几何的非线性模型，从线性系统的角度，利用ＲＨ控制方法和伴随技术，得到了一种新的鲁棒模糊导引律。这种方法能够以一个模糊Ｔ－Ｓ线性模型，来处理目标一定范围内的机动，而通过一系列模型的在线切换，来处理目标大范围内的机动。这种导引律具有快速、简便的特点和宽的初始阵位适用范围。仿真结果表明，这种导引律能够拦截任意机动的目标，获得较高的命中精度。

The Design of Optimal Fuzzy Guidance Law with Terminal Constraints

This paper studies the optimal fuzzy guidance law for intercepting arbitrarily maneuvering evader with the terminal constraints. The interception nonlinear model is approximated by the fuzzy T\|S linear model. A new fuzzy and robust guidance law is obtained by using the receding horizon control strategy and adjoint technique. That the evader maneuvers in small scope can be tackled with the corresponding fuzzy linear model. And that the evader maneuvers in large scope can be treated with the model\|switching among a series of linear model. This guidance law is easy to be implemented. The simulated result connotes that the guidance law can intercept arbitrarily maneuvering evader precisely.
