roll damping 中文意思是什麼
roll damping
解釋
滾動阻尼-
The aerodynamic characteristics of a projectile with wrap around fins are studied systematically in this paper, as follows : 1. the lift coefficients 、 drag force coefficients 、 pitch moment coefficients 、 pitch damping moment derivatives and roll damping moment derivatives are obtained from engineering calculation through looking wrap around fins as flat fins of the same projection aera
本文對某卷弧尾翼彈氣動特性進行了系統研究，主要內容與結論為: 1 .將卷弧翼按照相同投影面積的平板翼進行工程估算，得到升力系數、阻力系數、俯仰力矩系數、俯仰阻尼導數、滾轉阻尼導數曲線。 -
The rudder roll damping system is just the system whose controlled object is not square matrix. the input is rudder - order and the outputs are the roll angle and the heading angle. the input controls the two outputs
舵阻搖系統正是被控對象為非方陣的系統，它通過輸入_ r （舵令）來控制輸出（橫搖角）和（首向角） 。 -
The closed - loop transfer function matrix of such a system must be singular and an input controls two outputs in the system, so the closed - loop transfer function should be assumed a singular matrix whose elements are the fist - order inertia components, then the controller is designed. the control algorithm of closed - loop gain shaping is applied to the rudder roll damping system ( rrd )
考慮到此系統的閉環傳遞函數陣一定是奇異的，以及具有一個輸入控制兩個輸出的特點，在保證其中一個輸出盡量小而另一個輸出跟蹤輸入的前提下，將閉環傳遞函數陣即補靈敏度函數設為具有一階慣性的奇異陣，設計出控制器。 -
By analyzing the result, three most main factors influencing the calculation accuracy are found : the constitution of wave scatter diagram, interpolating the irregular wave and the estimating of roll damping coefficient
通過分析計算結果提出了影響計算精度的三個最主要的因素：海浪能量譜的構成、不規則波的合成方法、橫搖阻尼的估算。 -
The course keeping and the course tracking are well. through observing, analyzing and comparing the simulated curves with damping and those without damping, the roll reduction can reach 25 % or so
運用simulink工具箱得出加風、浪后系統的輸出曲線，通過觀察，可以看到舵角在有效范圍內變化，航向跟蹤和保持得很好。
