PI调节下光伏逆变器的分岔与混沌现象研究
Study of bifurcation and chaos for photovoltaic inverter with PI controller
摘要
Abstract
Regarding the photovoltaic (PV) inverter which uses current control method with PI controller as the research object, the discrete model of system is built by the stroboscopic map, and a new method which can find the duty ratio is given. Putting the input voltage of the inverter as the bifurcation parameter, the dynamic bifurcation diagram is obtained. With different bifurcation , parameters, numerical simulation of the output current is gained by the folded diagram, which illustrates the validity of the discrete model. Finally, the experiment waveform of the output current is obtained by RT-LAB experiment platform, and the discrete model is further examined. The study expands the range of research on the bifurcation and chaos from the inverter with proportional controller to the inverter with PI controller, and makes a further study for the nonlinear behavior of the PV inverter.关键词
