Adaptive nonlinear output feedback for transient stabilization and voltage regulation of power generators with unknown parameters

Abstract : This work presents a nonlinear adaptive output feedbak exitation ontrol, designed for a synhronous generator modeled by a standard third order model on the basis of the physially available measurements of relative angular speed, ative and reative eletri power and terminal voltage. The power angle, whih is a ruial variable for the exitation ontrol, as well as mehanial power and the impedane of the transmission line onneting the generator to an in nity bus, are not assumed to be available for feedbak. The feedbak ontrol ahieves transient stabilization and voltage regulation when faults our to the turbines or the transmission lines, suh that parameters (mehanial power and line impedane) may permanently take any (unknown) value. The ontroller reovers by adaptation the unknown values and simultaneously generates tra jetories to be followed by the states, that onverge to the new equilibrium point.
