Abstract :
For a class of three-loop architecture motion control system, two-stage closed loop identification is introduced to solve the problem of biased estimation. Using this method the bridge transfer function is identified firstly so that the control vector can be reconstructed uncorrelated with noise. Then, the plant can be estimated.
