| Abstract: |
| This work presents a control approach based on sliding-mode-control (SMC) to design robust H∞ state feedback
controllers for load frequency regulation of delayed interconnected power system (IPS) with parametric uncertainties.
Considering both state feedback control strategy and delayed feedback control strategy, two SMC laws are proposed.
The proposed control laws are designed to improve the stability and disturbance rejection performance of delayed
IPS, while stabilization criteria in the form of linear matrix inequality are derived by choosing a Lyapunov–Krasovskii
functional. An artifcial time-delay is incorporated in the control law design of the delayed feedback control structure to enhance the controller performance. A numerical example is considered to study the control performance
of the proposed controllers and simulation results are provided to observe the dynamic response of the IPS. |
