Developing, Implementing, and Assessing Decoupling Control for UTP Air Pilot Plant

This paper aims to develop, implement and assessing MIMO system for Universiti Teknologi PETRONAS (UTP) Air Pilot Plant. MIMO system is far more complex than SISO system as MIMO system has multiple interactions. Condition number which often related to MIMO system is the measurement parameter for degree of interaction between variables of the system and variable interaction is the dynamics between manipulated-process variable and controlled-process variable pair. The higher the condition number, the higher the degree of process interaction. Those systems can be very challenging to adjust or control one input from affecting another output because the outputs are reliant to more than one input. Small changes or disturbance in inputs can resulted into a major chaos in the output. Usually, a multi-loop control configuration is applied to MIMO system. However, if the process interaction is significant, it is wise to consider multivariable control strategies such as decoupling control
