| 摘要: |
| 针对新能源用DC-DC Buck变换器常规滑模控制需要同时检测变换器输出电压和滤波电容电流，提出一种基于super-twisting微分器（STD）的滑模控制器。与常规滑模控制器相比，所提出的控制方法只需检测变换器输出电压，无需测量电容电流，因此可以将电流传感器从控制环路中移除，从而简化控制系统。仿真实验结果表明，与常规滑模控制器相比，所提出的STD滑模控制具有更小的稳态误差，同时保留了对输入电压扰动和输出负载扰动的强鲁棒性。 |

| Abstract: |
| The conventional sliding mode control design for DC-DC buck converter needs to measure the converter output voltage and the capacitor current simultaneously. In contrast to this, the paper proposes an innovative super-twisting differentiator (STD) based sliding mode control for DC-DC buck converter. The STD based sliding mode control only needs to measure the converter output voltage. There is no need to measure the capacitor current, such that the current sensor can be removed from the control loop, thus the control system is simplified. It has been demonstrated by simulation results that when compared with conventional sliding mode control, the proposed STD sliding mode control can achieve smaller steady state voltage error and at the same time, the strong robustness against the input voltage perturbation and load resistance disturbance can also be preserved. |
