function [iq,id] = inv_park(iQ,iD,ang)
% This function computes the inverse park transformation to change
% the synchronously rotating dq stator variables to stationary dq 
% stator variables 
% Inputs:  
%         iQ = Synchronously rotating q-axis stator variable
%         iD = Synchronously rotating d-axis stator variable
%         ang = Synchronously rotating angle between 0-2*pi (rad)
% Outputs:
%         iq = Stationary q-axis stator variable
%         id = Stationary q-axis stator variable

iq = iD*sin(2*pi*ang)+iQ*cos(2*pi*ang);
id = iD*cos(2*pi*ang)-iQ*sin(2*pi*ang);
