Electric Vehicle Powered by Brushless Direct Current (BLDC) Motor

About the submission: This submission contains a set of models to show the implementation of electric all-terrain vehicles powered by BLDC motor. The model is built for the student teams participating in the electric BAJA competition where the vehicle is driven by a BLDC motor. The teams can use this example as a reference to build their own vehicle models by changing the parameters and subsystems.

Models

eATV (R2022b)

The model implements a closed-loop electric all-terrain vehicle using a Motor & Drive block. Irrespective of the type of motor, the model can be used for powertrain simulations. The model was built in R2022b version.

openLoopElectricAtv

This model implements an open-loop electric all-terrain vehicle powered by a BLDC motor with a low fidelity longitudinal vehicle dynamics.
The model is used for performing open-loop testing and for optimizing vehicle parameters.

closeLoopElectricAtv

This model implements a closed-loop electric all-terrain vehicle powered by a BLDC motor with a low fidelity longitudinal vehicle dynamics.

Product Requirements

The models are developed in MATLAB R2020b version and use the following MathWorks products:

1. MATLAB
2. Simulink
3. Simscape
4. Simscape Driveline
5. Simscape Electrical

Learning Resources

1. Motor Control: Watch this series to learn about brushless DC motor control. You’ll learn about the inner workings of a BLDC, and six-step commutation (trapezoidal control).

2. How to Design Motor Controllers Using Simscape Electrical: This video series will show you how you can model BLDC motors, investigate motor characteristics such as back-EMF voltage and torque, and design speed controllers using Simscape Electrical.

3. Physical Modeling Tutorial: These training materials will help your student competition team get started with modeling, simulating, and analyzing automotive systems.
