Analytic Framework for Blended Multiple Model Systems Using Linear Local Models
Leith, D. J. and Leithead, W.E. (1999) Analytic Framework for Blended Multiple Model Systems Using Linear Local Models. International Journal of Control, 72 . pp. 605-619. ISSN 0020-7179
In this paper it is shown that the dynamics of a conventional type of blended multiple model system are only weakly related to the local models from which it is formed. A novel class of velocity-based blended multiple model systems is proposed for which the dynamics are directly related to the local models. Indeed, the solution to the blended multiple model system, locally to a specific operating point, is approximated by the weighted linear combination of the solutions to the local models. Moreover, in contrast to conventional blended multiple model systems, the velocity-based blended multiple model systems employs linear local models, thereby providing a degree of continuity with established linear methods and, consequently, facilitating analysis and design.
