查询词典 autopilots

ABSTRACT The paper mainly studies the variable structure adaptive control theory for uncertain systems, and applicated the theory into the designs of bank-to-turn missile autopilots. The main contributions of the paper are as follows:(1) Under the condition that all the matched or mismatched parameter, input and disturbance uncertainties exist, a complete set of variable structure control system design and analysis method is proposed and investigated, which brecks throush the serious confines of variable structure invariance conditions theoretically and widen the application area of the VSC theory greatly.

本文着重研究了不确定性系统的变结构自适应控制理论，解决了目前变结构控制理论和自适应控制理论中存在且亟待解决的四个方面的问题，将获得的理论研究成果直接应用于倾斜转弯导弹的自动驾驶仪设计中，取得了很好的结果。
