| 摘 要： | 为提高拦截大机动目标的制导性能,应用变论域模糊理论,设计了一种模糊自适应的末制导律。将目标的机动加速度视为外界干扰,根据李亚普诺夫函数分析变论域模糊制导律参数的自适应律,保证了视线角速率收敛到0附近领域,从而确保了制导精度。仿真结果表明,所提出的变论域模糊末制导律在目标机动下可精确拦截目标,具有良好的鲁棒性能。

| Abstract: | A terminal guidance law based on the variable universe direct adaptive fuzzy approach is developed for intercepting maneuvering space targets.By defining the target acceleration as an unknown disturbance,the adaptive laws based on a Lyapunov function are developed to adjust the parameters of the fuzzy rules to guarantee the stability of the system.The guidance law not only keeps the angle rate of line of sight converging to zero between interception and target,but also guarantees intercepting all kinds of m... |
