PID Control using Coldfire V1

MWMinor — Mon, 02 Jul 2012 21:41:40 GMT

Hi there

Has anyone experience in developing a PID controller using a coldfire V1 device like the MCF51JM128...?

Is there anything "off the shelf" available...?

Thanks

Hello,

I have developed a PID controller as Processor Expert component (using integral numbers).

If this is of interest, I could publish it.

It was used to control a DC motor using a quadrature encoder as input, and having a PWM signal as output.

I have it running on S08, ColdFire V1 and V2, but as Processor Expert component it is universal.

Hi BK

Having a processor expert component that is a PID control function sounds interesting.

Thanks for your help

Hi MW,

This is right now for a DC motor (PWM and DIR signals) and using a quadrature encoder.

It probably does not match what you have to control, but maybe gives you an idea.

The PID is using integers (floating point would have been an overkill for my S08).

In any case you could either take the generated source code, or change the component(s).

The above article has links to the download page(s) as well.

Hope this helps,

Dear Eirch,

Could you give me a example project of PID, your post just some text, don't had project:smileyhappy:

Many many thanks.
