This letter proposes an unknown input zonotopic Kalman filter-based interval observer for discrete-time linear time-invariant systems. In such contexts, a change of coordinates decoupling the state and inputs is often used. Here, dynamics are rewritten into descriptor system by augmenting vector with inputs. A outer approximation feasible set then obtained prediction-correction strategy using i...

A new (descriptor) model transformation and a corresponding Lyapunov–Krasovskii functional are introduced for stability analysis of systems with delays. Delay-dependent=delay-independent stability criteria are derived for linear retarded and neutral type systems with discrete and distributed delays. Conditions are given in terms of linear matrix inequalities and for the 1rst time refer to neutr...

A major challenge in scene understanding is the handling of spatial relations between objects or object parts. Several descriptors dedicated to this task already exist, such as force histogram which a typical example relative position descriptor. By computing interaction two for given all directions, it gives good overview configuration, and has useful properties that can make invariant 2D view...
