Abstract： The bipolar DC micro-grid based on the Buck-Boost voltage balancer framework has been widely studied. The effective control voltage balancer keeps the positive and negative voltage of the system equal, to ensure the power quality of the system. Aiming at the control of Buck-Boost voltage balancer, a double integral sliding mode controller is designed. This method takes into account the nonlinearity and dynamic state of the system, and adopts double integral sliding surface to reduce the steady-state error. The experimental results show that compared with the traditional PI controller, the controller designed in this paper can effectively shorten the dynamic adjustment time and reduce the difference between positive and negative voltage.
Key words : Buck-Boost voltage balancer; bipolar DC micro-grid; double integral sliding mode controller
現(xiàn)有的文獻中，已經(jīng)提出多種電壓平衡器的結(jié)構(gòu),，本文研究常規(guī)的Buck-Boost電壓平衡器的控制,。Buck-Boost電壓平衡器大多采用PI控制器[5-6]，雖然PI控制器在一定范圍內(nèi)能獲得良好的動態(tài)響應(yīng)和穩(wěn)態(tài)效果,，但是大范圍工作狀態(tài)下很難取得良好效果[7-9],。滑?？刂剖且环N非線性控制,，具有全局穩(wěn)定、魯棒性強,、容易實現(xiàn)等優(yōu)點,。近年來，有學(xué)者將滑?？刂埔氲诫娏﹄娮酉到y(tǒng)的控制中,，并取得優(yōu)越的效果[8-9]。本文設(shè)計一種雙積分滑模(Double Integral Sliding Mode,，DISM)控制器運用在Buck-Boost電壓平衡器的控制中,。
