The H^∞ control experiment study for structure-acoustic system

Based on the H^∞ control theory,the feedback control model of structure-acoustic system is presented in this papers the feedback controller design problem is transformed into the H^∞ standard problem to solve.A H^∞ control system for enclosed space is also build up,which is based on the TMS320C30 DSP board.In experiment,the noise has been reduced 7 dB (A) in assigned frequency band.
