PID regulator



    The PID controller can be described by the equation:



where yr is the set point and y is the process output. The PID controller was originally implemented using analog technology that went through several development stages.
    Any standard transformation method can be used in the discretization of equation:

PID regulator equation

The proportional part:
PID regulator equation

The integral part:
PID regulator equation

The integration is approximated by:
PID regulator equation

which gives the following (forward euler) time discretization:
