Do Parallel PI Controllers Interfere with Each Other's Outputs in Matlab?

[San10]

I had a question related to modelling in Matlab. Will there be an interference in output signals when there are two PI controllers working parallely.
the input for both PI controllers is the same. the output signals are different as the P and I gains given to both are different.

Note: there is a switch used in order to use one particular signal received from PI controllers.

I want to understand the working of model in this case.
Thanks in advance!

Can you post a diagram for the setup? As long as the two outputs are not connected, and as long as the input impedance of each PID is constant (not modulated by feedback or other means), then I would think that the two PID controllers should not "talk" to each other...
