Invariance under discretization for positive systems

چکیده
Abstract Positive dynamical or control systems have all their variables nonnegative. Euler discretization transforms a continuous-time system into on discrete time scale. Some structural properties of the may be preserved by discretization, while other lost. Four fundamental positive are studied in context discretization: positivity, stability, reachability and observability. Both linear nonlinear investigated.

Invariance Preserving Discretization Methods of Dynamical Systems
In this paper, we consider local and uniform invariance preserving steplength thresholds on a set when a discretization method is applied to a linear or nonlinear dynamical system. For the forward or backward Euler method, the existence of local and uniform invariance preserving steplength thresholds is proved when the invariant sets are polyhedra, ellipsoids, or Lorenz cones. Further, we also ...
متن کاملOn the preservation of co-positive Lyapunov functions under Padé discretization for positive systems
In this paper the discretization of switched and non-switched linear positive systems using Padé approximations is considered. We show: 1) diagonal Padé approximations preserve both linear and quadratic co-positive Lyapunov functions; 2) positivity need not be preserved even for arbitrarily small sampling time for certain Padé approximations. Sufficient conditions on the Padé approximations are...
متن کاملRobustness of Positive Invariance Property for Continuous-time Systems
Two majors issues in the design of control systems are the direct integration in the control law of technological/safety constraints and the performance robustness of the closed-loop system with respect to parametric perturbations. In the last years, many authors have been treated the problem of constraints sat isfaction for controlled linear systems through the use of the positive invariance p...
متن کاملPractical Robust Positive Invariance for Large-Scale Discrete Time Systems
This note introduces practical set invariance notions for physically interconnected, discrete–time systems, subject to additive but bounded disturbances. We offer a concept which allows us to investigate invariance properties for each of the subsystems separately and, hence, to study invariance properties of the overall system in a sensible and decentralized way. The analysis part makes use of ...
متن کاملSteplength Thresholds for Invariance Preserving of Discretization Methods of Dynamical Systems on a Polyhedron
Steplength thresholds for invariance preserving of three types of discretization methods on a polyhedron are considered. For Taylor approximation type discretization methods we prove that a valid steplength threshold can be obtained by finding the first positive zeros of a finite number of polynomial functions. Further, a simple and efficient algorithm is proposed to numerically compute the ste...
