Adaptive performance control method and system for integrated microgrid of UPS system

The invention discloses an adaptive performance control method and system for an integrated microgrid of a UPS system. The method comprises the steps of building a constrained space state model of theUPS system, and determining the constraint on an output quantity and the boundedness of all closed-loop signals when a control target of the UPS system is clear; converting the constrained space state model into an equivalent constrained space model based on an error transformation method; representing an error between an actual output track and an expected output track of the equivalent constrained space model by using a parameter variable, and converting the initial constraint on the output quantity into typical stability control; designing a virtual controller for the parameter variable, and correspondingly designing an actual controller for generating a final control signal. In the embodiment of the invention, the control difficulty of the UPS system is reduced, a good control effectis achieved for linear loa
