This study provides a comprehensive review of existing active disturbance rejection control (ADRC) techniques for the control of non-minimum phase (NMP) DC–DC boost converter (DBC). A boost converter presents a challenging control task due to its non-linear and NMP dynamics while operating in continuous conduction mode. ADRC schemes, specifically those that claim improved performance for NMP systems, have been experimentally evaluated for voltage control of DBC. Additionally, a new way of incorporating known system dynamics into the control structure is proposed through a modified scheme. An averaged non-linear model of DBC is used in the simulation to analyse the effectiveness of control schemes and the results are experimentally validated on hardware. It is shown that the proposed method outperforms the reported model-assisted ADRC techniques while utilising only the system pole information.
