Many industrial applications, concerning flow process, need to change, maintain or simply monitor the level of liquid in a tank [1-4]. Some key points in designing such control systems derive from the evaluation of some relevant parameters that are difficult to measure, such as outflow coefficients or general leakage coefficients [2]. This paper analyses the possibility of integrating the extended Kalman filter in the control loop in order to determine the parameters influencing the regulator [5-10]. An interesting development of these algorithms is a diagnostic system which can evaluate leakage conditions by monitoring the variation of such parameters and prevent diseases.

Abstract
Many industrial applications, concerning flow process, need to change, maintain or simply monitor the level of liquid in a tank [1-4]. Some key points in designing such control systems derive from the evaluation of some relevant parameters that are difficult to measure, such as outflow coefficients or general leakage coefficients [2]. This paper analyses the possibility of integrating the extended Kalman filter in the control loop in order to determine the parameters influencing the regulator [5-10]. An interesting development of these algorithms is a diagnostic system which can evaluate leakage conditions by monitoring the variation of such parameters and prevent diseases.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
