Conventional photovoltaic grid-connected using PI current loop control, there are some shortcomings: low precision control system, on the system parameters perturbation robustness is not strong, rapid, no static error, and strong anti-disturbance load capacity is limited and so on. In order to improve the dynamic performance of the grid-connected PV inverter control system, reduce the hardware and...
To simplify grid-connected inverter control system, improve dynamic characteristics of the system, and reduce the hardware and software cost of inverter control design, the exponential sliding mode control (ESMC) and the square root sliding mode control (SRSMC) were designed. Theory testify of the sliding mode approach law applied in the grid-connected inverter was completed, and system stability...
