DC-Motor-Simulation

This is a collection of DC motor speed control simulation, including single(speed) loop and Dual(speed and current) loop speed control.

Requirement for matlab

Matlab/Simulink 2023b

Project review

This Project investigates DC motor drive systems, focusing on single-loop and dual-loop speed control systems, and simulates their behavior using Matlab Simulink. Our aim is to analyze and compare the performance of these two types of DC motor drive systems.
