“…The control strategy implemented in this laboratory is a decentralized PID controller (one for each loop). A detailed block diagram of this structure is given in Figure 16.b, where K is the proportional gain, T i the integral time, T d the derivation time, N is a parameter to limit the high frequency gain (N∈ [2,20]), and b is the set-point weighting parameter (b∈[0, 1]). By modifying the parameters of the PID controller, other variants, such as P, PI, or PD, are obtained.…”
