Design of a 2x2 Multivariable Control System with Two Monovariable Controllers and One Process Dedicated Decoupler.

For a multivariable process with strong input-output cross-interactions, the control system design is difficult to do using only monovariable controllers, one for each input-output (I-O) process channel. The purpose of this paper is to present a practical solution for controlling a heat transfer multivariable 2X2 process using two PID monovariable classical controllers and a 2X2 decoupler connected in front of the process, in order to provide a decoupled process.
