Fractional Transformation-Based Decentralized Robust Control of a Coupled-Tank System for Industrial Applications

Petrochemical and dairy industries, waste management, paper manufacturing fall under the category of process industries where flow liquid control are essential. Even when liquids mixed or chemically treated in interconnected tanks, fluid should constantly be observed controlled, especially dealing with nonlinearity imperfect plant models. In this study, we propose a nonlinear dynamic multiple-input multiple-output (MIMO) model. This model is then transformed through linearization, technique frequently utilized analysis modeling fractional processes, decoupling for decentralized fixed-structure H-infinity robust design. Simulation tests based on MATLAB SIMULINK subsequently executed. Numerous assessments conducted to evaluate tracking performance, external disturbance rejection, parameter fluctuations gauge effectiveness proposed The objective work provide framework that anticipates potential outcomes, paving way implementing reliable controller synthesis MIMO-connected tanks real-world scenarios.
