The Texas Instruments C28x family of processors has been designed to implement control applications, for example digital motor control and un-interruptible power supplies. We shall start here with a simple application. In this Laboratory, you will build a simulation model of a vehicle dynamics using Simulink, and then emulate it using the eZDSP-F2812 board.
Beginner; This is intended as the first complete project using Matlab and Simulink.
It is suitable for students who have only limited exposure to Texas Instruments DSPs before.
In developing this Laboratory, the following hardware and software were used:
Open VehicleDynamics.mdl .
Run the Model.
The input to the model is a ramp generator, which simulates smooth acceleration.
You will see the graphs of Horsepower and Vehicle Speed.
Double click on the “Vehicle Dynamics” block. This models the equation of motion using Simulink Blocks.
At present, the vehicle mass is 8000 kg.
We will now simulate a small compact car. Change the 1/m gain block to 1/1000 and change the b/m block to 2/1000.
Run the model again and notice the effect on maximum vehicle speed and how long it takes to reach maximum vehicle speed
You might also like to simulate a 35,000 kg lorry. Change the 1/m block to 1/35000 and b/m to 10/35000.
Double click on the “Engine Management” block. This models the gas in – horsepower out function of the engine.
Double-click on the Power Transfer Function
Change the shape of the Power Transfer Function. You may wish to change the gradient or make the plateau wider. Run the model.
Go to the Website of an automobile manufacture, and obtain the actual engine power transfer function for a real car. Run this in the model.
