Hi,
I am working on a model predictive control of inverter using a Microlabbox or DSpace 1102. Recently, I found that working with Microlabbox beyond 2e-5 us is a tough task. I came to know that, for dSPACE1104, there are slave PWM blocks to working with low sampling rates. But unfortunately, there are no such options in Microlabbox. I am aware of the s-functions based model but looking for an alternative to that. I request you to guide me in working with more complex models such as sample-based controllers at low sampling rates. please share some useful information in this regard.
Thanks in advance.
Dear Siva Kumar,
First dspace 1102 are the same with 1104 for this question,you can chois and specified sampling time that will became an integer multiple of pre-specfied sampling times blocks in simulink.
For more information about this subject, I suggest you to see links and attached file on topic.

Hi Mohamed-Mourad Lafifi, thanks for your help. But unfortunately, they did not help me. I need information about Microlabbox which is not the same as in 1104.
Hi Siva,
Here are additional references on Microlabbox.

Dear Siva kumar Gannamraju,
did you find a solution for How to reduce sampling time for dSPACE 1102 or microlabbox ?
thank you
These are the ways.
1. Get the supporting software for FPGA programming. Then you can operate a very low sampling rate.
2. Check for the turnaround time in a control desk. So that you can identify and fix the high computations.
3. If you still want any additional details, you can mail me at
