Outline of Final Research Achievements

This research proposes two new identification methods for modeling of dynamical control systems.
First, a notion from the robust control theory is exploited to define system transformation, which enables to construct a new continuous-time subspace identification algorithm.
Second, an identification method utilizing physical laws is proposed, where local models measured at small number of operating points are interpolated to yield a global model.
