N2 - The algorithm on controlling sound sources (speaker) intension and their controlling effect is theoretically investigated in unstable premixed combustion. Firstly, the equations of sound wave are deduced. Then, the formulations on controlling sources intension and controlling result are introduced according to the criteria making acoustic potential energy of combustor minimized and the expressions of acoustic characteristic in combustor followed. At last a detailed simple case is given, in which large eddy simulation technology is used for calculation of combustion field in order to decide the main fluctuating frequency of pressure in combustor.
