Hydrogenerator rotors : zero frequency of torsional vibration and resonance 水電機(jī)組轉(zhuǎn)子軸系扭振零頻的計(jì)算和共振分析
Furthermore , the constraint condition of the transfer function at the zero frequency and the phase invariability condition of transfer function are presented 與傳遞函數(shù)極點(diǎn)的理論關(guān)系,得到了傳遞函數(shù)低頻約束條件和傳遞函數(shù)相位不發(fā)生畸變的補(bǔ)充條件。
A kind of arithmetic of recursive least squares ( rls ) method with forgetting factor combined with model matching of zero frequency was adopted to identify the object online 采用了帶遺忘因子的遞推最小二乘和基于零頻率的模型匹配的聯(lián)合辨識(shí)算法對(duì)空調(diào)系統(tǒng)進(jìn)行在線辨識(shí)。
