Nonlinear output stabilization control for multimachine power systems
TL;DR: In this article, a robust decentralized nonlinear control scheme is proposed for multimachine power system stability enhancement, which consists of a novel dynamic direct feedback linearization (DFL) compensator through the excitation loop to cancel the nonlinearities and interactions among generators and a robust feedback controller to guarantee the asymptotic stability of the DFL compensated system considering the effects of dynamic output feedback and plant parametric uncertainties.

Robust control of a class of uncertain nonlinear systems
TL;DR: In this article, the robust control of a class of nonlinear systems with real-time-varying parameter uncertainty is considered and a technique is proposed for designing stabilizing controllers for both problems by converting them into scaled H∞ control problems which do not involve parameter uncertainty.
