1. Notations and structure of the PID controller

1.1 Notations and definitions

The structure of the control system is shown in figure 1 : the transfer function of the controller is denoted C (s ) and that of the process G (s ), where s is the Laplace variable. The transfer function of the compensated open loop is therefore :

H BO (s ) = C (s ) G (s )

and that of the closed loop :

HBF(s)=HBO​(s)1+HBO​(s)
