How to convert Fixed-in-Minor-Step to Continuous in Simulink?

Hi

How do I convert a Fixed-in-Minor-Step sample time signal to a Continuous sample time signal without changing solvers?

Yeah, how? What is the trick?

I have multiplied the FiM signal by a Continuous signal (equal=1) and it made it it continuous but that's dirty solution

There is a shipped SFunction 'sfun_d2c' which you could try using. It provides algorithms that essentially performs a linear extrapolation on the sampled data.

You can find an example using this S-Function at the following location in the MATLAB installation:

matlab\toolbox\simulink\simdemos\simfeatures\sfcndemo_d2c

You can use the command:

>>cd(matlabroot);

>>cd toolbox\simulink\simdemos\simfeatures

>>sfundemo_d2c

See if this helps avoiding the issue.
