Disturbance Decoupling Via Dynamic Feedback

1991
In the last twenty years there have been extensive studies of geometric methods in control problems. Geometric linear control theory started in the beginning of seventies and is based on the concept of controlled invariant subspaces introduced by Basile and Marro [BM] and by Wonham and Morse [WM].

Dynamics of pine ectomycorrhizae following root disturbance

Mycorrhiza
Ectomycorrhizae (ECM) and their hyphae may account for up to one-third of forest productivity, but we know little about their patterns of decomposition and recruitment. ECM decomposition rates are governed in part by the identity of the symbiont, while the species that colonize new fine roots are determined by a number of abiotic and biotic filters ...

Nonlinear Dynamic Model Evaluation from Disturbance Measurements

IEEE Power Engineering Review, 2001
The nonlinear nonsmooth nature of power system dynamics complicates the process of validating system models from disturbance measurements. This paper uses a Gauss-Newton method to compute a set of model parameters that provide the best fit between measurements and model response.

Forest Dynamics and Disturbance Regimes

2002
Temperate-zone forests have been shaped by fire, wind and grazing over thousands of years. This book provides a major contribution to the study of their dynamics by considering three important themes: • The combined influence of wind, fire and herbivory on the successional trajectories and structural characteristics of forests • The interaction of ...
