Chaotic Oscillation Control in Power System based on Adaptive Linear Feedback Sliding Mode Control

摘要

The power system is a typical complex nonlinear system. In some parameters, chaotic oscillation will be occurred in the power system. In this paper, a second-order power system is introduced and its chaotic dynamic behavior is analyzed. In order to suppress the chaotic oscillation of the power system, an adaptive linear feedback sliding mode controller is designed. Unlike the traditional sliding mode controller, the designed controller can estimate the disturbance of system via the adaptive control, so the upper bound of the disturbance does not need to be known. In addition, it also has good robustness. Simulation results demonstrate the effectiveness and the good robustness of the designed controller.
