D-Q axis current

I am applying a FOC control for an asynchronous Induction Motor.

The above model is to program a F2808 micro controller, from Texas Instruments. I applied a Open loop V/F control and I am converting the model into a FOC control in a step wise manner.I have 3 current sensing inputs to ADC, from which I am applying a clark and park transformation. the angle is calculated by using the flux model in which uses the speed in RPM from the motor. the clark transformation worked fined with a sine waves with 90° phase shift. Now I am facing the issues with park transformation. the model when tried to built causing errors.

Can any one help me with the error.
