N2 - This work describes the design of Robust Decentralized Controllers for a multivariable system by considering the parametric uncertainty due to parametric variation and interaction uncertainty due to non-diagonal elements of a plant. First the plant is considered for uncertainty modeling. Then three methodologies are used to design decentralized H∞ controllers and decentralized H∞ Fixed Order Decentralized controllers. The performances of these methodologies are compared for a highly coupled three tank system. The close loop system is analyzed for uncertainty, H∞ norm reduction, Nominal Performance (NP), Robust Performance (RP), Nominal Stability (NS) and Robust Stability (RS). The system has achieved 100% RS and NS, and remarkable RP, NP, H∞ norm reduction and time domain performance.
