Abstract

The invention discloses an adaptive optimal output feedback controller structure of an interconnected double synchronous generator system and a realization method thereof. The controller structure is used to control generator system I and generator system II. In this structure, the fuzzy observer is designed to estimate the power angle, power angular velocity and mechanical frequency of the interconnected dual synchronous generator system for the situation that the state is unobservable in practical applications, thereby reducing the control cost of the interconnected dual synchronous generator and overcoming The shortcomings of traditional state feedback control; then, use the traditional adaptive backstepping method to design an adaptive backstepping controller and estimate the performance index function of the interconnected double synchronous generator system through neural network technology and design the optimal controller of the system . Under the joint action of adaptive backstepping controller and approximate optimal controller, this control method can not only ensure the stable operation of two interconnected generator systems, but also reduce the performance index of the system.

Description

technical field [0001] The invention relates to an adaptive optimal output feedback controller structure of an interconnected double synchronous generator system and a realization method thereof, which can be used in the technical field of industrial process control. Background technique [0002] In recent years, the research of microgrid technology is becoming a research hotspot at home and abroad. In the microgrid system, wind power generators, photovoltaic generators, micro gas turbines and diesel engines are the main power sources, and they are all connected to the microgrid through inverters. In order to ensure the stable operation of the microgrid, the control strategy of the synchronous generator has attracted more and more attention of scholars. Synchronous generator power angle is an important measurable output that is very common in generator control systems. The turbine valve opening of the generator is a control variable that is often used in the generator syst...
