| Function | 
                             Description  | 
|---|---|
| PIDInit | 
                             Clears the delay line elements in the 3-element array located in Y-Data space and pointed to by controlHistory. It also clears the current PID output element, controlOutput.  | 
| PIDCoeffCalc | 
                             PIDCoeffCalc computes the PID coefficients based on values of Kp, Ki and Kd provided by the user.  | 
| PID | 
                             Computes the controlOutput element of the structure tPID.  |
