Overview
This project presents a systematic approach for modeling and analyzing RC, RL, and RLC electrical circuits using discrete-time linear dynamical systems. The objective was to understand how resistance, capacitance, and inductance influence circuit behavior. Series RLC circuits were modeled using state-space representations derived from Kirchhoff’s Voltage Law and then discretized for simulation in MATLAB. A comprehensive tuning process was developed and applied to design three RLC circuits: a resonator, a sensor, and a filter.
