Dynamic modeling of a generator/rectifier system

A nonlinear detailed model has been constructed for synchronous generators loaded with a rectifier bridge. This dynamic model is based on the description of the commutation and noncommutation stages. The switching instants depend on the state variables of the system. In order to be able to apply linear system theory for control design, an approximating linear model has been derived, based on application of the Floquet theory. Consequently, asymptotic stability analysis is possible with the linear model. Comparison with the full nonlinear model shows good resemblance.<
