Continuous-Discrete Interval Observers for Systems with Discrete Measurements

International audienceWe consider linear continuous-time systems with input, output and additive disturbances when measurements are only available at discrete instants. For these systems, we solve a state estimation problem by constructing a family of continuous-discrete time-invariant interval observers. These interval observers are composed of four copies of the studied system accompanied with appropriate outputs which give upper and lower bounds for the solutions.Nous construisons des observateurs par intervalles pour des systèmes avec des mesures discrètes
