The relationship between the error signal and gain parameters of PID controller is nonlinear, and , a normal controlled system＇ s step response figure , under the condition of ideal change of the three PID gain parameters in the different time , PID con troller.

但是，目前使用的PID控制器大多仍是传统的线性PID 控制器，其控制信号是通过将参考输入与被调节量的偏差及其微分、积分进行简单的线性组合来生成的，而且PID控制器的增益参数在系统动态响应过程中是固定不变的，不能反映偏差信号的变化l2j。

The assembled tweezer has been successfully utilized to direct the self-assembly of a series of dynamic [2]catenanes from three components via three different non-covalent interactions.

A final explosive change in register from interior to exterior is augmented at high tide by the breakwater that with each wave send a huge spray up into the air and crashing down into the adult pool, celebrating nature as uncontrollable, uncontainable process.

最后一个戏剧性标记室内到室外的转变在涨潮时透过防波提被强化出来；藉著每次海水的波送，激起的巨浪高升入天，浪花随之向下坠入成人池中，透过这样拥抱著自然野性和奔放的动态过程。

For example, if there are overexposure and/or underexposure, left and/or right peaks become large, and the remaining part of the histogram degenerates into thin strip on the bottom during normalization process.

放大倍数动态改变，以使至少20%的区域被使用，以方便观察直方图。裁剪的峰值会在顶端以红色标出。

This paper first elaborated the principle of SINS, some interrelated information,and the affect of renewed arithmetic to the system"s precision. Then, we studied thequaternion in traditional renewed attitude arithmetic. The quaternion is simple, andwhen run it into computer, it"s time saving. So, this arithmetic is often adopted byengineering. However, the quaternion brought unexchangeable error inevitably. Whenthe carrying body moves in highly dynamic situation, the error would become larger.So we should take effective measure to get over it.

本文首先论述了捷联式惯性导航系统的工作原理及相关知识，捷联惯导系统姿态更新算法对系统精度的影响；其次研究了传统的姿态更新算法中四元数法，该算法简单，计算量小，因而在工程中经常被采用，但是在四元数法中不可避免的引入了不可交换性误差，特别是在载体处于高动态环境时，这种误差就会很大，必须采取有效措施加以克服。

The very essence of research is that it is a dynamic venture into the unknown or partially known.
