| 英文摘要 |
| This paper is aimed at the problems of DC–DC converters in various applications, such as input disturbances,
load disturbances and electromagnetic disturbances. The traditional linear active disturbance rejection control (LADRC)
controller is improved according to the system model characteristics of full-bridge DC–DC converter. An ADRC controller
based on reduced-order extended state observer and proportional control is designed for the actual system, and the parameter
tuning process is optimized under the premise of ensuring system performance. Simulation and experimental results show
that the control system has better speed, robustness and adaptability than traditional PI control systems. It greatly simplifies
the problems of parameters selection in the design process of the traditional ADRC controllers |
