红稻数据
Examples
- The model of rrd is linearized to a fifth - order linear one , and then is reduced to a second - order one
研究并建立舵阻摇系统的非线性模型，并在matlab中通过编写s函数来实现。 - The main work of this paper is the heat transfer experiment in rotating cavity of an advanced aero - engine of rrd company
本文工作围绕rrd公司某型先进发动机高压涡轮盘腔内换热实验进行。 - The nonlinear mathematics model of rrd is researched and established , and is realized by programming in matlab . the controller designed is applied to the fifth - order linear model and the nonlinear one , and then simulated by simulink . the control performance is excellent
用设计好的二阶控制器对五阶线性模型和非线性模型进行仿真控制，运用simulink工具箱得到仿真曲线，从仿真曲线可看出此控制器具有良好的控制性能。 - 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 )
考虑到此系统的闭环传递函数阵一定是奇异的，以及具有一个输入控制两个输出的特点，在保证其中一个输出尽量小而另一个输出跟踪输入的前提下，将闭环传递函数阵即补灵敏度函数设为具有一阶惯性的奇异阵，设计出控制器。 - ( 1 ) taking the new br 700 gas turbine which is developed by rolls - royce deutshland as research object , the numerical simulation has been applied to the new structure of rotating disk system with pre - swirl nozzles on the rotating disk with ? turbulence model and with a new hybrid grid
( 1 )本文以rrd公司新研制的机种br700为研究对象，采用-湍流模型对带有预旋的新型旋转盘腔内的流动进行了数值计算。在旋转盘的计算中提出了一种新的网格剖分方法，计算的旋转雷诺数达到1 . 0 10 ~ 8 。
