Identification and Dynamic Weights for Lqg Control with Integral Action
The authors describe how to construct systematically a prefilter for the data entering the identifier, when the task of the latter is to provide a reduced-order plant model to be used for offset-free LQG control with integral action. The problem of choosing suitable dynamic weights for the control performance index is also addressed via a complementary identification procedure acting on the residual errors.
