| description | The invention discloses a photovoltaic VSG inverter control method based on an improved reaching law integral sliding mode, and relates to the technical field of photovoltaic power generation. The invention aims to enhance the robustness and the steady-state precision of the photovoltaic grid-connected VSG system. According to the control method of the photovoltaic VSG inverter based on the improved reaching law integral sliding mode, feedforward decoupling control is carried out on a three-phase inverter mathematical model under a dq coordinate system, independent control of dq axis voltage and current is achieved, non-matching uncertainty disturbance in a backstepping method compensation system is utilized, and the control precision of the photovoltaic VSG inverter is improved. An integral sliding mode controller is designed for a voltage outer loop subsystem and a current inner loop subsystem, and rapid response of the d-axis current, the active power and the reactive power of the inverter and accurate tra |
