摘　　要：建立了机动再入弹头攻击地面目标的随机数学模型,根据再入机动弹头攻击目标的要求,选择合理的代价函数和控制量的约束方程,利用随机最优控制理论,结合再入弹头的运动学与动力学方程,获得再入弹头的最优制导律.该制导律在存在状态噪声和观测噪声的情况下能有效完成再入机动弹头的制导,并使系统满足一定的约束条件.将此最优制导算法应用到某型再入弹头,通过计算机仿真验证了算法的正确性.The stochastic mathematical model about maneuverable reentry warhead attacking ground target was established. The reasonable cost function and restrict equations of control measure were selected based on the demand of maneuverable reentry warhead attacking ground target. The optimal control law of reentry warhead was acquired making use of the optimal control theory, kinematic and dynamic equations of reentry warhead. The guidance of reentry ma- neuverable warhead with states noise and observation noise, can be achieved by this guidance law and the system can satisfy the restrict terms. Applying the optimal guidance law in this paper to a reentry warhead, this optimal control law was proved effective through computer simulation.
