自动驾驶

The thesis is studying roll control of autopilots.

论文主要是针对自动驾驶仪中的滚转回路进行了研究：建立了滚转回路系统模型，完成了滚转控制通道数字化设计。

Take the BTT missile with airplane figure for example, the lateral-roll coupled and pitch self dynamics model was set up according to the flight condition. Two autopilots were designed and the simulation had been finished.

以某飞机型BTT导弹为例，根据其气动特点建立了俯仰独立、偏航-滚转耦合的气动模型，并分别设计了俯仰及偏航-滚转通道自动驾驶仪，对设计结果进行仿真。

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。

In nearly a dozen deadly accidents then, planes crashed after pilots flouted basic rules, such as by flying into violent storms and haphazardly programming autopilots. Then in June 1994, a China Northwest Airlines plane went down a few minutes after takeoff from the resort spot of Xi'an , killing all 160 aboard.

在那段时期，一连串飞机坠毁事故中都存在飞行员违反基本规定的现象，例如将飞机驶向剧烈风暴地区，或随意设定自动驾驶。1994年6月，中国西北航空公司一架飞机从旅游胜地西安起飞后不久坠毁，机上160人全部丧生。

Authorities at first blamed an engine explosion, but six months later, they charged five mechanics with improperly repairing and re-connecting a part of the autopilot system, in a way that would have made the plane nearly impossible to control.

调查部门一开始将事故原因归咎于发动机爆炸，但6个月后，5名机械师因此事故被追究责任，原因是他们对飞机的维修不当以及重新连接自动驾驶系统中某一部件后，造成飞机几乎无法控制。

The result indicates that the rotor downwash flow has an obvious inf luence on the missile, but with the control of autopilot the effect can be minished evidently.

结论认为下洗流场对导弹初始弹道的影响是显著的，导弹自动驾驶仪的控制作用可有效减小这种影响。

The use of radial basis function fuzzy network design for ship control is investigated.

引言船舶控制是船舶自动驾驶系统的基本组成部分。

Autopilot is an important sub-system of surface-to-air missile, which directly affects the homing capability of missile.

自动驾驶仪是防空导弹的重要子系统，其性能直接影响导弹寻的能力。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
