How to change the transfer function variable in simulink during simulation time

24 views (last 30 days)
Hi,
I have a Simulink model, where I need to change the transfer function coefficient during simulation run time. For example the TF is (1/1+sRC). Here R and C values need to change during run time. How to do that? Problem here is that the R value is calculated with the load current, that is (output voltage)/(load current). So I know the load current variation by calculating the R values. If anyone knows how to change the TF coefficient during runtime please help me. Thanks in advance.

Hi Swasthik,
If I understand correctly, the R and C values are changing dynamically. Just use blocks (integrators, subtraction, product, etc.) to implement the first order differential equation explicitly. The Transfer Function block is intended to be used with fixed parameters.
