STATE ESTIMATION - USING INTERVAL ANALYSIS

conference paper

English

In modern control theory, the mere knowledge of input/output values is often insufficient for system control - therefore the use of modern algorithms processing instant state values is inevitable. These values can't be always measured because it is often physically difficult to do so, or it is financially ineffective. Because of that state estimator are designed, which are capable of approximate calculation of the input/output state values. In case of linear systems, these estimators aren't very complicated and they function relatively reliably. Far worse situation is in case of non-linear systems and time variable systems. There are also frequent problems in failure incidents. The design of universal reliable estimator is very interesting task and this paper approaches one of possibilities.
