Active Disturbance Rejection Controller for RC circuit system

In electricity, resistance R and capacitor C are common components, and also are indispensable. The circuit with R and C looks simple, but in a sense, it shows some physical phenomenon behaviors. In this paper, we take RC system as the example, and implement control of the different series RC system with only using the second-order linear Active Disturbance Rejection Controller (ADRC). The simulation results show that the ADRC can plays good performance and robustness in the control of the RC circuits, where the stability analysis has effective influence on the uncertain systems´ future study.
