Algebraic Approach for Analysis and Control of a Water Tank System

Modern nonlinear control theory provides various powerful frameworks. Some of them are still either out of sight of the industry or too complex to be implemented. In this paper, we present and explain the key points of an algebraic framework of differential forms. Together with Mathemati ca based software package NEControl it forms a powerful basis toward the employment in analysis and control of various complex processes. The application is illustrated on the basis of the laboratory model of three serially connected water tanks, and comparison with the results obtained by using classical PID controller is presented.
