I am using a PI controller in the dq control circuit of 3 phase inverter and every time i run the model, I am getting this error:

Derivative of state '1' in block 'Assignment3_partA_b/PID Controller6/Integrator' at time 0.0 is not finite. The simulation will be stopped. There may be a singularity in the solution. If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances)

Note: the output of this PI controller along with the output of other PI controller is connected to a matrix concatenate.
