We just used a simple lookup-table for sin and cos. We just typed that thing into a big, ugly block of if-then statements. Worked great!

Hi Shawn,

This is a great write. Down to the point.

How did you manage to handle angles and arcs with this code ? This is one of the problems im facing and I have no idea how to handle it in a microcontroller with all the trignometry

Mr. Shawn,

Good afternoon!
This is TJ Sarmiento, a Mechanical Engineering student from Manila, Philippines. I have a project wherein I need to control the speed of a small windmill/wind turbine in relation to changing wind speeds. My control system should involve PID control. I plan to make an air duct with controllable guide vanes inside, controlled by some servo motor. To maintain constant exit air speed from the air duct, the guides vanes should be controlled so that my windmill outside will rotate at constant speed.

Sir, I’m starting from scratch, and I’m considering the use of PIC16F877A. Also, I still don’t have idea on the programming aspect. My proposed setup is shown on my attached PDF file (pls see attached file). Sir, please advise on what materials, components and accessories I should use.

Looking forward to your favorable response. Thank you.

-TJ

Hi, this is a master piece of work. I am working on a personal home research project. I am using multiple MCUs to separate concerns and have a better control of time based tasks. So I can easily introduce a separate MCU for PID using PIC which I am already familiar with. My question is how to modify the code to control Hitec servos instead of DC motors; I am using standard continuous rotation servos and Nubotics quadrature encoders. Thanks

Hi Shawn,

How difficult would it be to let the chip accept direction and step signals ?
(instead of spi signals)
I would like to use these pid controllers for a cnc system…

I am currently designing a motor control system for a small robot,I also plan to use a pic18 microcontroller for PID control.
I’m pretty sure that I am on the right track, however I don’t fully understand how a PID is used to do this.
If your document can help me to do that please send it to me
thanks so much!!!
