Closed Loop Co-simulation

Hello,

I am performing an induction motor co-simulation of the FEA model in Activate. As it is a closed loop system, I used a discrete delay block (1/z) for the output current which is to be compared with the current commands for generating the voltage commands via a PI controller. However, the discrete delay block is also slowing down the computation time. Is there any other method that I can use to speed up the processing time? Thank you.

Regards,
