TL;DR: In this article, an effective control law is proposed against matched and unmatched uncertainties for load frequency control (LFC) application in three-area interconnected power system, which has ability to vary closed-loop system damping characteristics according to uncertainties and load disturbances present in the system.

TL;DR: The proposed observer based controller is compared with an existing two-layer active disturbance rejection control (ADRC) and also validated on large power system at random load disturbance and the simulation results illustrate the robustness of proposed controller when subjected to load disturbances and non-linearities.

TL;DR: In this paper, a time delay-dependent H ∞-based nonlinear sliding mode controller for load frequency control (LFC) scheme has been proposed for N area power system, which uses Lyapunov-Krasovskii functional based on time delaydependent stability criteria and linear matrix inequalities optimisation.

TL;DR: This paper addresses the problem of observer design for the twin rotor multi-input-multi-output (MIMO) system which is a nonlinear system and Lyapunov theory is used to guarantee stability for state estimation and neural network weight errors.

TL;DR: The proposed controller has ability to vary closed-loop system damping property according to uncertainties and load disturbances and thus ensures asymptotic stability and enhances the integration level smoothly and reduces frequency deviation in the system.
