摘要（英）：

The invention discloses a single-phase grid-connected inverter control device based on a Lyapunov state function. The device comprises a reference current acquisition module used for collecting an output current of an inverter, a Lyapunov control module, a first control module, a second control module, a third control module and a fourth control module, wherein a collected reference current Iref(s) passes through the Lyapunov control module so as to generate a voltage signal uLyapunovl; a control function of the first control module is Q(s)e<-st>; a control function of the second control module is (img file= ' DDA0000722730580000011.TIF' wi=' 441' he=' 142'/)(/ maths); a control function of the third control module is (img file=' DDA0000722730580000012.TIF' wi=' 489' he=' 133'/)(/maths); a control function of the fourth control module is (img file=' DDA0000722730580000013.TIF' wi=' 507' he=' 135' /). The Lyapunov state function is adopted in the invention. Disadvantages that a repetitive control internal-model closed-loop system instruction signal period is delayed and a dynamic response speed is slow can be overcome. Dynamic performance of a control system can be fully guaranteed.
