ABSTRACT In this paper, two control schemes for boost converters affected by uncertainties in input voltage and load are proposed. The boost converter dynamics is redefined in terms of new state variables to facilitate the use of a disturbance observer that can estimate matched and unmatched disturbances. A sliding surface, which is new in the context of boost converters, is proposed to enable tracking and regulation of output voltage without requiring measurement of input voltage and load current. The stability of the overall system including the disturbance observer, the sliding variable and the output is proved. The performance of the schemes is assessed for regulation of output voltage and tracking of reference voltage by simulation as well as experimentation in which various types of uncertainties and various types of reference voltages are considered.

基于新型滑动面的升压 DC-DC 转换器的新型控制器

摘要 在本文中，针对受输入电压和负载不确定性影响的升压转换器提出了两种控制方案。升压转换器动态根据新的状态变量重新定义，以方便使用可以估计匹配和不匹配干扰的干扰观测器。提出了一种在升压转换器环境中是新的滑动表面，以实现输出电压的跟踪和调节，而无需测量输入电压和负载电流。证明了包括扰动观测器、滑动变量和输出在内的整个系统的稳定性。
