Abstract

This study presents detailed designs for components of a boost converter, and parameters of a flexible sliding mode controller suitable for the boost converter applications. The converter performance is evaluated in a comparative way in terms of removing the overshoot and the oscillations in the load voltage during a sequence of reference voltages at fixed resistive load. The converter response is observed, firstly, using the equivalent duty cycles to produce the same sequence of reference voltages. Then, the converter response is observed after inserting the designed SM controller. The output voltage of the converter is monitored during tracking the desired reference voltage before and after inserting the controller. This study demonstrates a high priority of the boost converter effectiveness after involving the SM controller to the system. MATLAB/Simulink software is adopted to simulate the presented design and to observe the system performance to confirm the improving converter performance in terms of removing the overshoot and oscillation from load voltage during tracking the reference voltages.

利用滑模控制改进升压变换器比较研究

本研究提出了升压变换器元件的详细设计，以及适用于升压变换器应用的柔性滑模控制器的参数。在固定电阻负载的一系列参考电压期间，以一种比较的方式来评估变换器的性能，以消除负载电压的超调和振荡。首先，使用等效占空比来产生相同的参考电压序列，观察变换器的响应。然后，在插入设计的SM控制器后，观察变换器的响应。在插入控制器前后跟踪所需参考电压期间，监测转换器的输出电压。该研究表明，在将SM控制器引入系统后，升压变换器的效率具有高优先级。采用MATLAB/Simulink软件对所提出的设计进行仿真，观察系统性能，以证实在跟踪参考电压时，从消除负载电压的超调和振荡方面改善了变换器的性能。
