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

Ray,

Please be more specific in your description. Proportional controllers usually do not connect to function generators so it is not clear exactly what you are trying to accomplish.

Which parts of your system are hardware and what kind? Which are implemented in LV (which version)? What are the inputs and outputs to both the hardware and software? What frequency range do you need? If you have specific problems with a part of your LV program, posting an example showing the problem is very helpful.

When you say the output disappears, do you mean that the pulses stop? That may simply indicate a 0% or 100% duty cycle.

Many inidviduals with a wide range of experience monitor this forum and will try to help if we understand what you are trying to do.
