Abstract
The direct feedback linearization (DFL) technique together with the gain scheduling multiobjective control theory are further developed and applied to design nonlinear excitation compensators, which selectively eliminates system nonlinearities and deal with plant uncertainties and interconnections between generators. Digital simulations show that control scheme achieves unified transient stability in the presence of parametric uncertainties and significantly sudden changes in the network parameters.
