Level Control of Hopper Tank Process Using Model-Based Controller

In industries, many processes are nonlinear, in-order to understand and analyze the process, linearization step is involved. The nonlinear process taken is Hopper tank process. This paper highly concentrates on level control of Hopper tank process. Conventional PID, internal model controller, modified internal model controller are developed and tested in MATLAB simulation environment. Time domain and error criterion analysis are done and better performances are highlighted.
