Abstract
In order to improve the static and dynamic performance of the single-phase grid connected inverter with LCL filter, a sliding mode control strategy based on an improved switching function is proposed. This control strategy , from the point of switching function model, analy-ses the model of the system and obtains its state equation . By selecting proper sliding mode surface,it gets the equivalent control, puts forward a sliding mode controller using improved switching function and then proves the system stability by the second Lyapunov method. At last, it builds the inverter simulation experiment using MATLAB, and the simulation results show that the inverter using this strategy has a good dy-namic response performance, and its total harmonic distribution of grid current is 0. 41%.关键词
