“…To solve the above problems, this paper applies multi-index nonlinear design to uncertain power systems with uncertain parameters and external interference, combines it with robust control theory and adaptive control theory, proposes a multiindex nonlinear robust adaptive control method, and gives its closed-loop stability proof [14,15]. In [38,39], a decentralized controller based on Lyapunov theory for excitation control of multi-machine power systems ensured global asymptotic stability and realized voltage regulation through excitation control. In [40,41], For the multi-electromechanical power system including largescale photovoltaic energy storage power station, the multi-objective holographic feedback control method is adopted.…”
