Delay-independent stabilization for steam valve opening of multi-machine power system with sector actuator
具有扇形执行器的多机电力系统气门开度的时滞无关镇定(英文)

A time-independent decentralized controller and a robust decentralized controller have been developed for the steam valve opening of multi-machine power system with sector saturating actuator. The nonlinear interconnected function is first converted by trigonometric transformation into quadratically bounded inequalities in the subsystem states; and then, linear matrix inequality (LMI) sufficient conditions for the closed-loop multi-machine power system and uncertain system to be asymptomatically stable are derived based on Lyapunov stability theory. A two-machine infinite-bus system is considered as an application example. Simulation results demonstrate the effectiveness of the proposed method.
