Proportional controller connected to a function generator

[ray thomas]

Hi....

We'd like to connect some output from a proportional controller to a function generator which
produces a square pulse with variable duty cycle.

The question is what proportional controller to use here and if there is any examples related?
And how to produce this square pulse with a high frequency, while some controllers do not support
any thing more than 1kHz? In addition, if it exceeded this, something wrong happens to the output and disappears?

Thanks in advance
Ray

Hi Ray,
I understand that you want to use a proportional controller to regulate the duty cycle of a square wave that you will generate. We have many options of how to implement a system that will do this, but additional information about what you need to do and what hardware and software you already possess or would like to purchase will help us define the best solution for you.

(1)Do you already have a proportional controller or function generator that you want to use in the system?
(2)Are you using LabVIEW or another programming language?
(3)What sort of requirements will your system have? What hardware platform are we using (ie. PC, PXI, Laptop)? What type of square wave do you need to generate?

This information will serve as a good starting point, and any additional information you can provide will help greatly.
