Summary: | The invention discloses a self-adaptive valve control method for a nonlinear power system, which aims at a single-machine infinite bus system with a main valve controller, and designs a self-adaptive controller based on an event triggering mechanism under the condition that part of information of the system is unknown and an output sensor has disturbance. The controller controls the power angle of the generator to act according to the expected requirement by adjusting the opening degree of a valve, and actual tracking control over the power angle is achieved. The method not only considers the interference on a rotor of the generator, but also considers the interference on the power angle of the generator along with the change of the angular velocity of the generator, and the upper and lower bounds of the two interferences are unknown; the power system interference considered by the method is more complex, so that the control system designed by the invention has stronger robustness; and the event triggering me |
