Design and Control of A Twin Tank Water Process AbstractThe paper is concerned with the design of a twin tank water process and experimental evaluationof feedback and cascade control structures to achieve a desired water level in the second tank byadjusting the water supply to the first tank (feedback only structure) and the water level setpointof the first tank (feedback/cascade structure). Detailed, first principles-based, dynamic models ofthis non-linear and interactive process have been developed and compared to experimental datawith high accuracy. Furthermore, this experimental study entails and discusses the design of thetwin tank process and associated instrumentation, real time data acquisition and control inLABView, process modeling, controller design, and evaluation of the performance of differentcontrol structures in a closed loop manner. It was found that a combined feedback and cascadecontrol structure outperforms the simpler feedback only control structure. This work wasperformed as partial fulfillment of the requirements of the Senior Capstone Project course incontrols and instrumentation. Student experiences are summarized and the need for effectiveproject management methods is emphasized.Note: this student led paper is to be considered for poster presentation.
