The BLDC motor phases are controlled by the commutation logic provided to the three-phase inverter. The motor and inverter subsystem consists of a buck converter to step down the input voltage. It consists of a battery source which consists of cells in series where each cell is an RC equivalent circuit. The model outputs the vehicle velocity based on the input duty cycle. So, here is the open-loop model that we have developed using Simscape that enables you to rapidly create models of physical systems within the Simulink environment. To give an example, while in simulation, you can find the reason why your powertrain is unable to track the drive cycle.Īnd finally, you can convert models into production code. You can find and fix errors in the design phase. For example, whether to go with a simple gear assembly or to use a chain drive. Imagine you have a simulation model of your electric vehicle. ![]() ![]() So, with this let’s get started and welcome you all to the MATLAB and Simulink Racing Lounge. ![]() We hope you will find the video useful and will implement the learnings to develop your vehicle model. The video will also provide information on how you can use the model as a reference for optimizing certain vehicle parameters, performing simplified emergency brake tests, running a vehicle on a bump, and finally performing closed loop simulation to track the drive cycle and measure the state of charge. We will see how by combining various physical systems such as electrical, mechanical we can easily model an ATV.įor the video, we will refer to the ATVs used in off-road student competitions where the vehicle has a rear-wheel drive and is driven by a BLDC motor. In this video, we will see how we can model an all-terrain electric vehicle or in short ATV.
