  Performance and Analysis of PI Controller using Characteristic Ratio Assignment Method for Coupled Tank Process

  By T. Elizabeth Rani, Samson Isaac J

  Abstract: Control the level of the liquids is a critical need in many industrial processes. Often the tanks are so coupled together that the levels interact and exhibits a nonlinear behaviour. Control of coupled tank system using conventional PI controller, result in poor performance. In this paper the modelling and controller design for coupled tank liquid level process using characteristic ratio assignment (CRA) method is implemented. CRA method is an approach …

  Level Control of Tank System: Comparative Approach

  By T. Elizabeth Rani, M. Lavanya, K. Shanmuga Priya

  Abstract: Level measurement and control and monitoring are important for many products and processes in a diverse range of industries including manufacturing, storage and service industries. In this paper liquid level in the cylindrical tank is to be controlled at desired value. The composite controllers of proportional integral controller and proportional integral derivative controller was designed using Ziegler Nichols tuning for the cylinderical tank system. The fuzzy logic controller was implemented …
