Ho to control a regulator with a ramp generator?

[Les]

I need to automatically control a regulator using a voltage ramp generator,
and am not finding much in the way of help doing google searches, etc.

The ramp generator is easy... controlling the regulator has me stumped...

Thanx for any help...

What kind of regulator are you trying to control?
What does the ramp look like?
What does the ramp generator look like?
What effect are you trying to achieve from this arrangement?

What kind of regulator are you trying to control? I need ~0 to 400v output
What does the ramp look like? sawtooth
What does the ramp generator look like? 74ls590 counter driving a dac.
What effect are you trying to achieve from this arrangement? ramp a power
supply output voltage.

Well, he also said, "Nice software" when he should have said, "Nice
firmware" or "Nice wetware".[1] <leer, snort>

I've seen some of those on high class ho's. But I don't know if you could
pay any ho to control a regulator.

Maybe she will reg-you-later

power supply output voltage.

Use the DC output of the DAC as the reference. If it is 0-5 VDC, use a 400
to 5 divider on the power supply output. You may need to do some
compensation in the feedback if the ramp rate is fast, and it may have
problems if the power supply is a switching type or if there are large
capacitors.
