Abstract :
In this paper, we propose the partial time delayed feedback control of the chaotic dynamic behavior of the voltage-mode controlled DC-DC buck converter. In this control strategy, the control input is applied to the system intermittently, i. e., the input is added to the system during certain intervals of time defined by the switching rule. We do not apply the control all the time, thus saving on the energy consumption. The efficacy of the proposed method is also proven numerically. The theoretical justification will be introduced in a future paper.
