Equivalent sliding mode control for multi-level buck converter
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.
