Limiting State Estimation of Switched Interval Systems with Metzler-Takagi-Sugeno Models

The paper deals with interval observer design for fuzzy switched positive systems. systems are represented by the Takagi-Sugeno models, premise variables depending on a measurable part of state vector. Stability conditions proposed structure formulated via linear matrix inequalities to ensure nonnegative system estimation. method allows compute lower and upper bounds under assumption that disturbance bounded. properties approach illustrated in numerical example.
