A virtual closed loop method for closed loop identification

  title={A virtual closed loop method for closed loop identification},
  author={Juan C. Ag{\"u}ero and Graham C. Goodwin and Paul M. J. Van den Hof},
Indirect methods for identification of linear plant models on the basis of closed-loop data are based on the use of (reconstructed) input signals that are uncorrelated with the noise. This generally requires exact (linear) controller knowledge. On the other hand, direct identification requires exact plant and noise modelling (system in the model set) in order to achieve accurate results, although the controller can be nonlinear. In this paper, a generalized approach to closed-loop… CONTINUE READING
