Application of Active Disturbance Rejection Technology in Boost Converter

摘要

In order to make the boost converter be of better performance, by analyzing the characteristic of the classical PID control, a new type of nonlinear PID control method active disturbance rejection control (ADRC) is proposed. Taking the control strategy of Boost converter as the study object, the active disturbance rejection control is applied to the control strategy of Boost converter. The controlled system not only has good dynamic characteristics, but also has strong robustness to the variations of system parameters. The basic principle of parameter tuning for active disturbance rejection control is introduced, and the simulation of active disturbance rejection control of Boost converter is carried out and compared with PID control.
