Closed-loop PID Controller with Measurement Studio

[Michael Baxter]

I'm in the process of implementing a PID controller in C# with Measurement Studio. I realise that Windows XP cannot provide real-time performance, but as the cycle-time is quite slow I'm wondering whether this is really a problem.

I'm intending to have the controller driven from the .NET Timer class, and will be be using a cycle-time of 100mS.

Although I'm familiar with the implementation of a PID, any example code for C# would be very useful.

Any recommendations or advice on what I'm doing will be greatly appreciated!

Many thanks,

Michael

If you can use .NET Framework 2.0, consider using the Stopwatch class instead of the Timer class. Stopwatch utilizes the computer's multimedia timer (if available) to provide better accuracy and resolution than the Timer class.

Drohacek,

Although my gratitude is a little late, I would like to thank you for pointing me in the direction of the Stopwatch class, this has been very useful.

Many thanks,

Michael

You're welcome; I glad it was helpful.

BTW, what PID controller can be programmed with C#?  What programming hardware do you need to do this?

Thanks,

Scott

Nervermind, misunderstood topic.
