摘　　要：该文基于最优控制理论,在性能指标为控制能量最小的前提下,对垂直拦截机动目标的导引律进行了推导,得出无级变速鱼雷在垂直命中条件下攻击机动目标的导引律。该导引律分别从鱼雷速度的切线和法线方向上对鱼雷进行控制。通过计算机仿真,验证了所推导的导引律的有效性。Based on the optimal control theory, the paper deduced an optimal and perpendicular impact guidance law for intercepting a maneuvering target perpendicularly. Under the pre-condition of minimum energy consumption, the guidance law thus deduced controls a torpedo with infinitely variable speeds in the tangential and normal orientations of its velocity. The effectiveness of the optimal guidance law is verified by simulation results.
