An error sensor strategy is a key step in implementing an active structural acoustic control(ASAC).Controlling the first few order acoustic radiation modes of a plate shows to reduce efficiently its total sound radiation at low frequency.A new sensing strategy based on acoustic radiation modes for ASAC is proposed to minimize acoustic radiation from a vibrating plate.By measuring the vibrating velocity distributions at a few points of the plate and solving the underdetermined equations of the radiation mode expansion,the adjoint coefficients of the first N radiation modes can be obtained.They are used as input of controllers to form an error sensor strategy based on radiation modes and corresponding active control strategy.For a clamped-clamped plate,numerical results from active control show the feasibility of this error sensor strategy.
