Regulated Voltage Simulation of On-board DC Micro Grid Based on ADRC Technology

Abstract

Output voltage is an important index of on-board DC micro grid, and its stability is affected by many aspects. In the process of power generation, there exist multiple disturbances like speed fluctuations, load changes and time-varying parameters. If various influence factors are not effectively compensated, it will reduce the effectiveness of the system simulation and control precision of practical application. To deal with the problem, an ADRC was applied to on-board DC micro grid and simulated under severe interference conditions. Simulation results based on ADRC were compared with those of the traditional PID controller. The research shows that on-board DC micro grid using ADRC can compensate external disturbances effectively, and has a highly regulated voltage output performance, which verifies the feasibility of the proposed method.
