A Novel Active Vibration Control Method for Helicopter Fuselages Based on Diffusion Cooperation

Algorithm 1

Steps of secondary path trade-off quantization standard.

               Steps

1) actuator 1 action, response amplitudes

2) actuator 2 action, response amplitudes

3) actuator J action, response amplitudes

4) response amplitude matrix C

5) quantization threshold is b(0<b<1)

6) for i=1:length (C)

  for j=1:length (C)

    if (C(i,j)< bmax(C,[],2))

      A(i,j)=0;

    else

      A(i,j) =1;

    end

   end

  end

7) combination matrix A=A+A^T+I
