| 摘 要： | 针对导弹在拦截机动目标的特点,以最优控制中的线性二次调节(LQR)和滑模变结构(SMVS)为理论基础,推导出一鲁棒最优制导律。它综合了LQR和SMVS的优点,不仅脱靶量和消耗能量小,而且对目标机动等干扰不敏感,具有鲁棒性。仿真结果表明,所得制导律具有良好的性能,具有一定的应用价值。

| Abstract: | According to the characters of the missile intercepting the maneuvering target,a robust optimal guidance law is obtained on the basis of both linear quadratic regulator(LQR) and slide mode variable structure(SMVS).The guidance law absorbs the advantage of both LQR and SMVS,and it not only minimizes the miss distance and control energy,but also is not sensitive to disturbance,such as target maneuver,so it has good robustness.The simulation results show that the guidance law has good performance and values in application. |
