本文描述了飞机上多电平降压型变流器的等效滑模控制的设计与实现。多电平降压型变流器广泛应用于输入电压变化和大功率应用领域，是一个多输入、多输出、强耦合的非线性系统。针对多电平BUCK变流器设计了一种强鲁棒的等效滑模控制器，以降低其对参数变化和负载扰动的敏感性。给出了详细的设计步骤和参数选择方法。仿真结果表明，与传统的PID控制器相比，采用等效滑模控制的多电平Buck变流器在输入输出扰动下具有良好的动态响应和较强的鲁棒性。
This work describes the design and implementation of the equivalent sliding mode control for Multi-level buck converter in aircraft applications. The multilevel buck converter has been applied in the field of variation of input voltage and high power application, and is a nonlinear system with multi-input, multi-output and strong coupling. This paper designed a strong robust equivalent sliding mode controller for multi-level buck converter to reduce the sensitivity to parameter variations and load disturbances. The detailed design procedure and parameter selection method are presented. Simulation results show that, compared with the PID controller, the multi-level buck converter controlled by the equivalent sliding mode has good dynamic response and stronger robustness under the disturbances in input and output.
