Advancement of Active Disturbance Rejection Control and Its Applications in Power Electronics

The powerful control ability of the active disturbance rejection control (ADRC) method has attracted much attention from both the academic and industrial communities. This method successfully inherits the advantages of the conventional proportional integration (PI) control method, such as error-driven way, simple structure, and low design complexity. In addition, it also absorbs the observer technique from modern control theory. All these factors make the ADRC method show a big potential to be widely adopted in practical industrial applications. To facilitate this development trend, in this work, some advancements of ADRC are discussed in detail, and three typical applications in the power electronics field are briefly introduced, such that the engineers can have a more intuitive understanding of this method and the academics could recognize some topics that still need to be further researched.
