This paper deals with the control methods of high power electro-hydraulic speed servo control system used in an aeroplane engine simulating rig. 文中研究了用于飞机发动机地面模拟台的大功率电液速度伺服控制系统的控制方法。
The result of simulation by the software Matlab shows that signal attenuation and phasic excursion in high frequency is feasible for high speed communication over power networks in aeroplane. 仿真结果显示,飞机供电网络对高频信号的衰减和相位偏移影响不大。
The advantage of high speed railway on environment protection compared with aeroplane from the view of sustainable development is analyzed and some suggestions on high speed railway construction of China is presented as well. 文中从可持续发展的角度,分析了高速铁路的环保优势,并对中国建设高速铁路应注意的环保问题提出了建议。
