Chaotic Oscillation Suppression of the Interconnected Power System Based on the Adaptive Back-Stepping Sliding Mode Controller

The second-order interconnected power system is investigated in this paper, and the dynamic characteristics of the system under the disturbance of load and electromagnetic power are analyzed through the Lyapunov exponent and Poincaré maps. A adaptive back-stepping sliding mode controller is designed to control the chaotic motion in the power system. Theoretical analysis and numerical simulation results show that the controller can effectively suppress the chaotic oscillation.
