An unstable condition, which leads to self-excited pressure oscillations beyond 170 dB, is chosen as control target. Keeping the inlet air temperature, the air mass flow rate and the overall equivalence ratio, respectively, at 700 K, 78 g/s and 0.50, different secondary fuel injection strategies are examined. One is a steady injection method and the other is a feedback control, which was designed by the mixed H(sup 2)/H(sup infinity) control algorithm. The feedback control with three percent of secondary fuel performs peak pressure reduction of 27 dB, which is almost 10 dB larger than that of the steady injection method., 資料番号: AA0049500044, レポート番号: JAXA-SP-06-006}, title = {アクティブ制御による振動燃焼の抑制}, year = {2006} }
