查询词典 proportionality factor

PI arithmetic is utilized in fuzzy controller to adjust the proportionality factor of fuzzy controller automatically.

模糊控制器与工业过程控制中常用的PID控制器相比具有一定的优点，而它的一个最大缺点就是精度不太高。

The simulation on a system of boiler drum water level control indicates that the fuzzy controller of self-tuning proportionality factor based on PI arithmetic can improve the performance of fuzzy control system and can control the fallacious water level.

为减小模糊控制器的误差，最常用的就是将PID控制与模糊控制结合起来，从而构成模糊PID控制。然而由于引入了积分作用，使得控制过程的响应时间大大增长，失去了模糊控制响应快速的特点。

This formula indicates that the resolution of the panoramic receiver is pro-portional to its bandwidth,and the factor of proportionality ζ depends upon the typeof the IF filter and the detector.

公式表明，全景接收机的分辨能力与其通频带成正比，比例系数ξ取决于中频滤波器和检波器的程式。

Based on the Knothe time function, the progressive prediction of surface subsidence due to underground mining was established, and the factor of proportionality describing the influence of geological and mining conditions was determined when there was no measured data in practice. A method of periodic pressure distance to divide the total working face into certain elements considering the mining rate or mining duration was proposed.

详细分析了单参数的Knothe时间函数、双参数的Sroka-Schober时间函数和Kowalski 广义时间函数的优缺点及其相互关系，建立了应用Knothe时间函数进行地表动态移动变形预计的原理、无实测资料矿井时间参数的确定方法和开采单元划分的周期来压步距法。

This value is used to compare the strength of materials, but a safety factor is applied when making design calculations, to bring the working stress well below the limit of proportionality.

此值被用来比较材料的强度，但是当设计计算时，要用一个安全系数，使工作应力低于比例限制。

But in [ 1 ] there were several restrictions on the proportionality factor A in the stress-strain rate relations, such as supposing that A...

本文取消了对λ的这些限制。而文献[1]所研究的λ=cr~n(n=0或-1)的情形，只是本文的一个特殊情况。

Then J =μp, where the proportionality factor μ is called the Coulomb coefficient of friction.

于是J＝μp，式中的比例因子μ被称为库伦磨擦系数 2。

The model was simulated by Matlab. The control sequences of different flow proportionality factor with feedback gain were compared. Through comparing sample data, the result reveals that air traffic flow in the airspace unit has been improved.

利用Matlab对系统进行了仿真，对不同流动比例系数下得到的控制序列和反馈增益进行比较，通过采样数据的比较，得出的结果显示，空域单元的飞行流量得到改善。

Load Proportionality Factor curve can entirely describe the buckling process of the PIP systems.

以分析不稳定平衡问题的改进Riks方法被证明为高温海底管道屈曲分析的有效算法，得到的弧长－载荷比例因子曲线能够充分地描述双层管道的屈曲失稳过程。

self-tuning proportionality factor ; fuzzy control ; drum water level

基于此，本文提出了一种采用PI算法调整模糊控制器比例因子的模糊控制器，该控制器
