The 2x2 process reported below has to be controlled
The process is controlled using a decoupler and two PIs ( R1(s) and R2(s) ), each one controlling the corresponding output signal.
The goal of the control system is to maintain the output of the processe as close as possible to the set point references,
avoiding the cross effects between the first input and the second output and vice versa.
The package contains two models in which the process has been controlled using the decoupler
(see DecoupledControl )
and not
(see NoDecoupledControl )
Process Variables and set point references without decoupler
Process Variables and set point references with decoupler
The images show how the different control schemes react to the set point changes. The decoupler based scheme performs better than the one without.
