Simulation of RFOC of asynchronous machine

Hi,I have a problem in simulation the indirect rotor field oriented control,the error like in the image attached. I attach also my simulation. Anyone who know this problem,help me please. Thanks.

This error happens when very large or infinite values are fed to integrator blocks, e.g., due to a division by zero (1/0 = inf). Solvers have problems integrating such values and different integration methods can give different results. Also, models that are unstable or on the edge can quickly accumulate. For this particular model, later MATLAB release should be able to handle this better.
