Decentralized Internal Model Control based Proportional-Integral controllers (IMC-PI) are designed and their performances are evaluated on a real time laboratory scale coupled tank process. It is a well known multi input multi output (MIMO) process with nonlinear behaviour. The experimental quad-cou...
