Dear Sir/Madam,

Hello, I'm using dSpace in conjunction with Simulink (Matlab) to run a
dual-pump control system. We are running two continuous flow pumps in a
pulsatile manner. In order to do this, we've used two pulse generator in
Simulink to create two separate waveforms, one which dictates the voltage
for the left pump and one which dictates the voltage for the right pump. We
then use the controlboard on dSpace to control the various pulse-generator,
and hence pump, paramters.

This is our problem:

Two of our inputs are for the period of the pulse generators, one for each
pump. Unfortunately, if you change one period, the pulse-generator
immediately changes the settings, and the pulse waveforms go out of phase.
We want to be able to change one of the periods without causing this phase
shift.
What we had thought about was having a single input box on the controlboard
that would change both period inputs simultaneously, so that there is a
single input box controlling two different pulse-generator parameters.

Is this a possibility?

Regards,
Cihan
