Dynamic Systems and Control Engineering

Following our discussion of translational and rotational mechanical systems, we will now extend our mechanical modeling approach (via the system decomposition technique) to electrical circuits. As in Ch. 2, we begin by considering the fundamental elements from which many electrical systems are built, and we review the corresponding mathematical element laws and electrical circuit diagrams. Then, moving forward, the focus shifts toward the rules that govern the interconnection of these elements as complete circuits and subsystems of series and parallel elements. Through these discussions, we will find that, just as Newton’s second law guided our modeling approach for mechanical systems, our treatment of electrical systems will follow Kirchhoff’s voltage and current laws.
