Hello, I am currently researching the control of a Stewart platform simulation. I would like to input the necessary values by dividing them by the step size and using a MATLAB function block to deliver the input values in real-time. Is it possible to receive the calculated input values from a script file into the function block and deliver these values in real-time for each step according to the simulation time?

I want to input the values calculated in the script file into the MATLAB function block as data, with time and step settings, and have the block calculate the 8 prism joint displacements. These displacements should be divided into steps over the simulation time and delivered in real-time.

Hi @석준

In order to obtain the calculated input values from a script file within the function block and provide these values in real-time for each simulation step, I have a workaround that you might consider trying.

Please follow these steps:

Add a “MATLAB Function” block to the model.
Use a “Bus” block to combine all outputs from the 'parse motion' block.
Connect the “Bus” created in Step 2 to the input port of the “MATLAB Function” block from Step 1.
Link the output of the “MATLAB Function” block from Step 1 to the input port of the “parse motion” block.
Set the priority of the “MATLAB Function” block from Step 1 higher than that of the “parse motion” block.
Incorporate domain-specific logic into the newly created “MATLAB Function” block and assign initial data to the relevant properties.
