摘要

摘要: 针对大气层外机动目标的拦截问题,分析了轨控发动机作用下拦截器与目标的相对运动规律,并据此提出了拦截能力的估计方法.根据轨控发动机能够修正的视线转率上限和最短工作时间设计了开机曲线.结合开机曲线和拦截能力的估算方法提出了基于模糊逻辑的导引规律.该导引规律根据专家经验制定模糊规则,利用相对距离和拦截能力作为模糊推理系统的输入对发动机的开机曲线进行调整,结合继电器方式的发动机开关机规律形成制导指令.针对两种典型的目标机动方式,通过仿真验证了该导引规律对机动目标进行拦截的有效性.

Abstract: The relative motion law between the target and the interceptor was analyzed when the divert thruster was on or off. An estimator of the interception ability was proposed based on the relative motion law. On-off conditions for the divert thruster were designed according to the shortest working interval of the divert thruster and the upper boundary of the line-of-sight rate that could be restrained. A novel terminal guidance law was proposed based on the estimator and the on-off conditions. The guidance law took advantage of the experts- experiences to construct the fuzzy rules and adjusted the on-off conditions of the divert thruster based on the relative range and the interception ability. A relay on-off method was utilized to control the divert thruster. The effectiveness and the performance of the fuzzy guidance law are demonstrated through the simulation in which the guidance law is applied to intercept two kinds of maneuvering targets.
