Research on Passivity-based Control of Buck Converter Based on Active Disturbance Rejection Control

doi:10.11985/2020.01.010

Abstract

Abstract:

Passivity-based control (PBC) strategy can guarantee the stability of the system due to its energy dissipation characteristics. Therefore, the Buck converter is studied by PBC. However, PBC will have static error when the system parameters change or suffer disturbance. For this problem, the active disturbances rejection control (ADRC) strategy combined with PBC is used, namely inner loop PBC and outer loop ADRC. Compared with other control methods, this control strategy can ensure the system's large signal stability and the system’s fast recovery performance when subjected to disturbance, and has good robustness. Finally, the simulation model is built in Matlab/Simulink for simulation results, which verify the correctness and effectiveness of the proposed control strategy.

Key words: Passivity-based control, Buck converter, active disturbance rejection control
