Current cooperative control of multiple DC-DC converter systems with inductive load

Abstract:
Considering the tracking error and synchronization error of power system, a sliding mode cooperative control strategy based on extended state observer is proposed to solve the influence of load impedance inconsistency and load mutual inductance coupling on current dynamic consistency. Finally, Matlab / Simulink is used to model and simulate the system, and compared with the current cooperative control based on PI control. It is verified that the output consistency of the cooperative control strategy proposed in this paper is better and the current response speed is faster.
