Watch this tech talk series to learn about the basics of PID control.

To simulate this system, we created a mathematical model of the motor in Simulink and using a random chirp signal and the auto-tune functionality of the PID block arrived at a set of P, I and D gains for this model. We decided that a PID controller was the best control scheme for the low-level control of the motor. Next, we moved on to the control aspect of our problem. After a few simulations we settled on a simple color thresholding algorithm that is efficient and serves our purpose. Now that we have a data stream from the sensor, we tried a few different algorithms to achieve our objective – locate the ball in the image.

Once you download the free MATLAB Support package for USB webcams, sampling data from a camera, in MATLAB, is as easy as vidObj = imaq.VideoDevice( 'winvideo',1) We started by trying to identify the ball. These tutorials follow the same approach. MATLAB and Simulink provide many different tools to design simulations so you can test different scenarios and edge cases enabling you to build robust code. Simulation is the cheapest way to test algorithms. Some common examples are lane keep assist systems in self-driving cars where a camera detects lanes and steering commands are computed or an autopilot in cruise mode where an IMU is used to estimate orientation and wing flaps commands are computed to maintain a desired orientation. This is the principle behind many autonomous systems – use sensor information to compute control commands. The embedded computer, is used to take in a data stream from the sensor (camera) identify the ball position and compute actuator commands to keep the object in the center of the camera image. We created a ball-tracking system where a camera mounted on a servo motor is used to track a green colored ball.

This tutorial series will teach you how to generate low-level code from MATLAB and Simulink, through the lens of a simple autonomous system. Through these video tutorials we hope to teach you how to convert your MATLAB and Simulink algorithms in low-level C/C++ source code that can be integrated into other independent code bases or executables that can be deployed directly to an embedded system. So how do you take your algorithms from MATLAB desktop to these embedded systems? The answer is code generation. But what next?Īs a student competition team there is a good chance that you are working with embedded systems – tiny computers that are the brains of your racecars, airplanes, boats, robots or the various other thingamajigs that are trying to make this world a better place. In my many conversations with MATLAB users, the most recurring theme is always “MATLAB and Simulink are my go-to to prototype and simulate algorithms”. There are more than 5000 universities around the world where MATLAB is taught to students from Science, Technology, Engineering and Math disciplines.

But, why is this important? MATLAB is a multi-paradigm high-level programming language used by more than 2 million engineers and scientists world-wide. What is Code Generation?Ĭode generation is the process of generating low-level code directly from a high-level programming language or modelling environment. Connell, our regular guest blogger (… we should call him co-author of this blog …) wrote this article. I would like to start by wishing all of you a Happy New Year! In the spirit of the New Year and trying out new things we want to introduce you to our latest series of student competition tutorials on code generation.
