Simultaneous Identification of Multiple LTI Plants Using Multiple Models, Switching and Tuning

The multiple models, switching, and tuning methodology is used in this paper to identify simultaneously multiple linear time-invariant (LTI) plants. Two model assignment strategies are also presented. These strategies cause the models to organize themselves so that at any given instant only one model adapts to each plant. The choice of the assignment strategy and the performance criteria play an important role in the manner of both the convergence and the switching between models.
