摘　　要：针对Boost变换器中负载的不确定性或干扰不满足匹配条件的情况,设计了鲁棒反步滑模控制器,可使Boost电路的输出电压快速达到期望值,且稳态误差很小。最后用仿真结果验证了本文所提方法的可行性。The problem of the uncertain load and interference in the Boost converter is addressed. By applying the back-stepping sliding controller the output of the Boost converterconverges to its expectations rapidly and accurately. The simulation results demonstrate the feasibility and effectiveness of the new method.
