Embodiment Construction
[0061] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the embodiments provided by the present invention are not intended to limit the invention.
[0062] The method for quickly suppressing the chaotic oscillation of the dual-machine interconnected power system of the present invention first carries out a mathematical model on the dual-machine interconnected power system, and then designs the fast Terminal sliding mode surface and the adaptive law of uncertain parameters according to the fixed time stability theory, and then passes The nonlinear control law is derived theoretically and the controller is designed, and the upper bound of the stable time range is determined according to the relevant lemmas of the fixed-time stability theory and the stability analysis of the Lyapunov function, and finally the control effect is verified by numerical simulation;
[0063] Such as Figure 6 As shown, the specific...
