DC MOTOR

Overview

---

Goals

The objective of this task is to create a mathematical model of a simple DC (Direct Current) motor and afterwards to simulate its operation with MATLAB – either with its SIMULINK graphical programming environment or with an appropriate m-file from the command window.

Learning Objectives

Upon completion of this project the students will be able to: • describe the operation of a simple electromechanical system by means of differential equations • convert the basic mathematical model of the system from differential equations to a representation in the state space • simulate the obtained state space mathematical model in MATLAB with its SIMULINK graphical programming environment • simulate the obtained state space mathematical model in MATLAB by means of a m-file

Context

One of the most common electromechanical systems used in actuators in different types of control systems is the DC (Direct Current) motor. It is a rotary electrical machine that converts direct current electrical energy into mechanical energy which is used to drive different machines. It is very useful for students of different engineering degree courses to be able to model and simulate such motors.
