Predictive actuator fault‐tolerant control under ellipsoidal bounding

International Journal of Adaptive Control and Signal Processing, 2015
SummaryThe paper is devoted to the issue of a robust predictive fault‐tolerant control for linear discrete‐time systems with an application of an ellipsoidal inner bounding of a robust invariant set. The crucial issue is to maintain the state of the system inside the robust invariant feasible set, which is a set of states guaranteeing the stability of ...

Ellipsoid bounding estimation for kinematic geodetic positioning

Measurement, 2016
Abstract In kinematic position estimation, a Kalman filter procedure is often used to provide improved solution benefiting from the history information. However, the optimal Kalman filtering solutions are subject to precise function models and statistic knowledge of noises, which may be difficult to obtain in advance.

Ellipsoidal Bounds of Elastic Composites

Journal of Applied Mechanics, 2012
The formulation of rigorous bounds for the physical properties of composites constitutes one of the most fundamental parts of applied mechanics. In this work, the so-called ellipsoidal bounds, as a generalization of the Hashin-Shtrikman spherical bounds, are formulated for elastic moduli of multiphase composites.

State bounding with minimal volume ellipsoids

UKACC International Conference on Control. Control '96, 1996
The paper presents recursive algorithms for guaranteed state estimation using ellipsoidal bounds on the state of the system and the process and observation noises. Alternative techniques are used in the observation update to find an ellipsoid containing the feasible set.

Bounding ellipsoids for ray-fractal intersection

Proceedings of the 12th annual conference on Computer graphics and interactive techniques - SIGGRAPH '85, 1985
Recently published papers have shown that, with appropriate intersection algorithms, the rendering of many procedural objects is possible with all the advantages offered by the ray-tracing techniques. In the case of stochastic surfaces, the intersection can be computed by a recursive subdivision technique.

Limiting Behaviour of Bounding Ellipsoids for State Estimation

IFAC Proceedings Volumes, 2001
Abstract Ellipsoidal technique is an advantageous and helpful tool in state estimation of dynamic systems with bounded disturbances; it gives a reliable outer approximations on reachable sets. In this paper the problem concerning asymptotic behaviour of ellipsoidal estimates is considered for linear discrete-time systems without measurements.

Review and Comparison of Ellipsoidal Bounding Algorithms

1996
This chapter is concerned with the problem of robust system identification when no statistical information is available on the noise, but only a bound on its instantaneous values is known. First, various ellipsoidal outer bounding (EOB) algorithms are presented in a unified way.
