Longjie Zhang, Yong Chen, Esam H. Abdelhameed · 2024
This paper concentrate on the finite-time optimal control for the interconnected power systems with switching communication topology. The finite-time ADP-based optimal controller (FTADPOC) is proposed for the finite-time stability of the interconnected power systems (IPSs). Firstly, the consensus error model with switching communication topology of the IPSs is given. Then, the finite-time optimal controller solved by the HJB equation with the value function in the finite-time stability space is constructed. Furthermore, based on the finite-time optimization theory, the finite-time critic network for the approximation of the value function is implemented to solve the optimal controller, and the corresponding finite-time convergence of the proposed tuning law is illustrated. Finally, the result analysis on the interconnected power systems illustrates the effectiveness of the proposed FTADPOC.
