DEVELOPMENT OF MULTI INPUT MULTI OUTPUT COUPLED PROCESS CONTROL LABORATORY TEST SETUP

Multi Input ? Multi Output (MIMO) processes are very commonly found in many chemical unit processes. Control of such MIMO processes is always challenging due to coupling between inputs and outputs. Even after very significant efforts made by the research fraternity, control of coupled MIMO process is still an open research issue. Computerized and easy to use laboratory scale set up is very essential to investigate performance of different control algorithm on MIMO process. An attempt is made to develop low cost, configurable, computerized and smaller size multi input multi output coupled process control laboratory test setup. The proposed set up has capability to interface with user friendly LabVIEW platform. With the help of this interface the user can easily deployed any newly developed algorithm and verify on this laboratory scale test set up. The performance of the developed set up is checked with different controller tuning conditions as well with different coupling condition of MIMO process. The performance confirms the functionality of the developed set up.
