摘　　要：针对Buck变换器中负载的不确定性,研究了Buck电路的鲁棒控制问题。针对Buck电路中的误差系统利用终端滑模控制的方法,可使Buck电路的输出电压快速达到期望值。最后用仿真结果验证了本文所提方法的可行性。Aiming at the uncertain load in the Buck converter, the problem of robust control is studied. Aiming at the terminal sliding mode control is applied in the error system of Buck circuit, it may cause the output voltage in Buck circuit converges to its expectated value rapidly. The simulation results are investigated to show the feasibility and effectiveness of the new design method.
