摘要
建立了机动再入弹头随机数学模型,根据攻击目标的要求选择合理的滑模变结构开关面。利用随机变结构控制理论,并结合再入弹头的运动学与动力学方程,获得再入弹头的变结构制导律,并证明了滑动模态的可达性和击中目标时刻满足要求的终端条件。通过计算机仿真验证了所推导的制导律的正确性及对干扰和系统参数误差的鲁棒性。上述变结构控制算法对再入机动弹头制导系统的设计具有一定的应有参考价值。
The Stochastic mathematic model of maneuvering reentry warhead was proposed, and the rational slide switch surface was chosen based on the desire of attacking ground target. The variable structure guidance law was obtained with the stochastic variable control theory and kinematics and dynamics equation of reentry warhead, and it proved the sliding surface is reachable and the terminal condition is satisfied. Through the computer simulation, this guidance law is proved effective and is robust to the disturbing variable and system parameter error, and it is valuable for the design of guidance system in the theory and application.
