In airplane design, structural nonlinearities cannot be avoided. The structuralnonlinearities arise from worn hinges of control surfaces, loose control linkages,material behavior and various other sources. In the flighting, the aerodynamicnonlinearities also cannot be avoided. The aerodynamic nonlinearities can benegligible when the speed of the plan is not very high;but when the speed of the planis supersonic or highly supersonic, it cannot be negligible.

在飞机设计中，结构非线性是不可避免的，结构非线性源于控制其表面的旧铰链，松散的控制器联动装置，材料性能和其它的来源；在飞机的飞行中，气动的非线性也是不可避免的，对于飞行速度不是很高的情况，气动的非线性是可以忽略的，而对于超音速以及超高音速的飞机来说，气动的非线性是不可以忽略的。

Significantly, the fundamental issue of controlling a flying machine seems to have been addressed in only the most perfunctory way by most of those who sought to build a successful flying machine.

值得注意的是，根本的问题控制飞行机似乎已得到解决，只有在最敷衍的方式，大多数人谁寻求建立一个成功的飞行机器。

The key of the simulation is to select a suited set of models and parameters which represent the motion and the echo of moving targets, Because the perform of microwave radars operating over the moving targets is very complicated.In this paper, we discuss how to simulate the motion of targets with a method of parameters simulation. And then we get a track clearly through controlling the flight parameters and the time increasing. The way reduces the error.This paper also particularizes the prime parameter of the echo--Radar Cross Section which is influenced by many factors.

对于目标的实时运动特性，本文采用了航迹的参数模拟法，通过控制目标的飞行性能参数与时间增量的大小来模拟目标的真实运动，避免了多种因素所引起的飞行误差，效果良好；此外，本文详细分析了表征运动目标回波特性的雷达截面积与雷达波长、目标姿态、极化方式及视角的关系，在此基础上，考虑了RCS的两种起伏特性以及天线对其的调制作用，得出了快、慢起伏目标回波的仿真数据，并对二者进行了比较。

Just over 100 years since the first sustained and controlled heavier-than-air powered flight, flying machines are now commonplace, used for transport, freight, warfare, rescue and pleasure just for starters.

仅仅在100年以来的首个持续性和控制重于空气的动力飞行，飞行机器现在已是司空见惯，运输，货运，战争，救援和高兴地在首发只用了。

Periodic fluid pulsation in aeroplane hydraulic piping could induce fluid-construction vibration and lead to fatigue damage. It is impossible to find the error sensor's optimization location because of the pressure standing wave, and the pulsation attenuation effect is not perfect when adopting pulsation attenuation at single point. For this reason, a distributed active control method of fluid pulsation was presented. To avoid stationary point in all aviation states, several fluid pulsation actuators and error pressure sensors were placed along the piping. The second fluid pulsation produced by actuators can counteract the primary pulsation brought by aviation piston pump and make the mean pulsation of whole piping minimum when adopting adaptive feed- forward control and the filtered-X least mean square algorithm.

针对飞机液压能源管路系统中的周期性流体脉动诱发流固耦合振动，导致管路疲劳损伤的问题，针对管路中存在压力驻波特性，在采用单点消振时寻找误差传感器最佳布局位置困难而引起脉动抑制效果不理想的缺点，提出了一种分布式流体脉动主动控制方法，即沿管路不同位置布置多个主动消振阀和误差压力传感器，在任意飞行阶段，避开压力驻波点，以误差压力传感器的脉动测量值为控制目标，采用一种针对周期脉动主动控制的自适应前馈控制法和多通道自适应滤波－X LMS算法，调整控制器参数，使主动消振器产生的次级脉动与管路中的初始脉动相互抵消，达到整个管路中的平均流体脉动最小的效果。
