Presents the design of longitudinal control for ASTOVL lift-fan aircraft, a multi-variable, strong-coupling, complicated nonlinear system to make the system nonlinear offset and decouple, and the method used for linear system in designing the system to gain expectant flying qualities and the combination of aerodynamic control surfaces with thrust vectors to delay the control surfaces getting into saturation, and the minimum N-norm generalized inverse theorem of weighted generalized inverse adopted to apportion the moments commands, which make the control surfaces gain appropriate deflection and the simulation results to verify the dynamic inverse control laws designed really make the system nonlinear offset and decouple; when one command is given, only this output will response, and others do not response; when all commands are given together, the responses will be just the linear superpose of the response of each command, therefore the operation of the pilot will be simplified greatly.

摘 要： ASTOVL升力风扇飞机是多变量、强耦合、复杂的非线性系统，采用非线性动态逆理论设计控制律以实现系统的非线性对消及解耦，然后，采用线性系统的设计方法对系统进行设计，以使系统获得期望的飞行品质。同时，考虑到ASTOVL升力风扇飞机是由气动舵面和推力矢量融合作用的，为了延缓各舵面进入饱和的时间，采用加权广义逆中的极小N-范数广义逆定理分配力矩指令，从而使各舵面达到适当的偏转角。并将所设计的控制律进行了仿真，结果验证了所设计的动态逆控制律使系统实现了非线性对消和解耦，单个指令作用时，只有该项响应，其余不受影响；所有指令作用时，其结果就等于单个指令作用时的线性叠加，这样使驾驶员的操纵大大简化而易于控制，从而大大降低了飞行事故率。

However, to their surprise,"ironer" was a fully-intelligent pilotless aircraft, what they had to do is to train this "computer-controlled pilot" into a killing machine with independent combatting ability.

而更另他们没有想到的是，"铁蛋"竟然是一架全智能的无人驾驶飞机，而他们所要做的就是训练这位"电脑驾驶员"成为一个能够独立作战的杀人机器。

At the driver-side window is Ralph, who takes them all back to Krantz.

在驾驶员位置的窗户旁是拉尔夫，他将迈可一伙押回到"将军"的所在。

The pilot shut off the motors and glided down to the landing field.

驾驶员关了发动机，滑行降到机场上。

To launch a hot-air balloon, the pilot first makes sure the basket is tied securely to the ground, so it doesn't suddenly fly off.

想要让热气球升空，驾驶员首先要确定篮子有牢牢的绑在地上，这样气球才不会忽然升空。

The following appeared in a letter to the school board in the town of Cent erville.

Centerville高中的所有学生都应该被要求参加驾驶员教育课程。

Did you see the other driver's license plate number?

你看见了另一位驾驶员的车牌号码吗？

A pilot vehicle system mathematical model containing nonlinear control elements of the flight control system is established by the describing function method; the limit cycle of PVS is determined; the relation between the limit cycle and pilot induced oscillation and the influence of nonlinear control elements on PIO are explored.

采用描述函数法建立了含有非线性控制系统的人机系统数学模型，确定了系统的极限特性，探讨了极限环与驾驶员诱发振荡之间关系和操纵系统非线性因素对PIO影响等。

The remnant nis the difference between the actual pilot output and the linear approximation to it.

剩余值n是驾驶员的真实输出和它的线性近似之差。

First and foremost, we exposed just eight crew members — we typically flew with a pilot, copilot, loadmaster, and a second loadmaster who also acted as a scanner — and only two aircraft to the enemy threat, as opposed to three aircraft and eighteen crew members had we used the older aircraft.

第一个也是最首要的，相对于旧型号飞机我们要用3架飞机和18名机组成员执行任务，我们只有8名机组成员——飞行时我们的标准组成是一名驾驶员，一名副驾驶，一名装卸长，还有一名装卸长助手，他通常也扮演巡视员的角色——和两架飞机暴露在敌人的威胁里。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
