The keys to the development trend of cpcs ? electronic - electric cpcs are the control method and control law . in this study , a fuzzy logic control was proposed to accomplish the electronic - electric control of the sapc . a fir digital filter is applied after compared with several other digital filters to deal with the fluctuating pressure signal 针对压力信号在采集过程中出现波动较大的问题,本文在比较了多种数字滤波方法后,选择了fir滤波方法对采样数据进行处理,消除了数据采集中的高频噪声,从而实现对采样数据的平滑处理,为控制系统的实现打下基础。
Experiments about the influence of aeration on the dynamic pressure on the original riverbed show , aeration will obviously increase the fluctuating pressure on the original riverbed . 3 . experiments about the influence of aeration on the dynamic pressure on the bottom of scour hole show , the influence of aeration on the dynamic pressure on the bottom of scour hole is ruleless 试验研究了掺气对冲坑底部脉动压强的影响,结果表明:无论冲坑深度为多大,坑底脉动压强均方根值沿程分布与不掺气时相比,没有确定性的规律,射流掺气后,冲坑底部的脉动压强有时增加,有时反而减小。
