提出一种基于脉宽调制技术和滑模变结构控制技术相结合的新型直流变换电源控制策略，设计了一种连续电流模式下的升压直流变换电源滑模变结构控制器，将3．2V单体锂动力电池变换为满足携行电台供电要求的12V工作电源。通过Matlab／Simulink环境下构建控制器仿真模型，并对负载电阻和输入电压变化情况下的控制器性能进行仿真实验，结果表明该升压直流变换电源滑模变结构控制器在大范围扰动情况下的输出电压变化并不明显，稳态误差较小，动态性能良好，鲁棒性强。

A strategy which connects the pulse width modulation with sliding mode control was put forward and a boost DC converter sliding mode controller in continuous current mode was designed, using DC-DC conversion technology that changes the single low-voltage lithium battery of 3.2 V into the working power station of 12 V. Building the controller simulation model in Matlab / Simulink environment, simulating controller performance in the case of changing the load resistance and input voltage. Simulation results validate its performance in the large-scale disturbance, and show its good dynamic performance, robustness, and smaller steady-state error.
