摘要
In this paper, the analysis of linear Active Disturbance Rejection Control (ADRC) is carried out. A brief generalized mathematical analysis of this control technique is presented, where modifications to the existing control law is done. The mathematical formulations are followed by application on a second-order ADRC. Moreover, the resistance to input channel and measurement disturbances are considered, and a measurement filter is proposed for inclusion in the system. The generalized analysis is done for the second-order ADRC. Validation of the mathematical results and conclusions is done by considering the voltage control of a single phase DC-DC Buck and Buck-Boost converters. The systems are tried for disturbances of various frequencies, and also comparative analysis using the existing and modified control laws is done, and verified against the mathematical analyses.
