Nonlinear state estimation by Extended Parallelotope Set-Membership Filter

ISA Transactions, 2022
In this paper, we propose a state estimation method called the Extended Parallelotope Set-Membership Filter that provides a higher estimation accuracy than existing methods for discrete-time nonlinear systems. The Extended Parallelotope Set-Membership Filter is motivated by the fact that the iteration operations in existing methods generate much ...

Set-membership subband adaptive filters

2008 3rd International Symposium on Communications, Control and Signal Processing, 2008
In this paper, the concept of set-membership (SM) adaptive filtering is extended to the subband adaptive filters (SAFs) and a novel SM-SAF algorithm is presented. The proposed algorithm exhibits superior performance with significant reduction in the overall computational complexity compared with the ordinary SAF.

Least trace extended set-membership filter

Science China Information Sciences, 2010
To improve the consistency of estimation result, a least-trace extended set-membership filter (LTESMF) is presented for a class of nonlinear stochastic systems, which has linear output and unknown-but-bounded noise. Feedback technique is used instead of the intersection of ellipsoid-sets in the measurement update. The feedback parameter is optimized in

SET-MEMBERSHIP NONLINEAR FILTERING WITH SECOND-ORDER INFORMATION

IFAC Proceedings Volumes, 2005
In this paper, we develop a numerically efficient scheme for set-membership prediction and filtering for discrete-time nonlinear systems, that takes into explicit account the effects of nonlinearities via local second-order information. The filtering scheme is based on a classical prediction/update recursion that requires at each step the solution of a

Set-membership filtering strategies for multipulse coding

2006 IEEE International Symposium on Circuits and Systems, 2006
This paper describes a new class of multi-pulse coders based on bounded-error identification. Multi-pulse coders provide effective representations of speech signals by extracting linear prediction parameters and approximating the effect of excitation signals with strategic sparse impulse sequences.

Set-membership filtering for complex networks with constraint communication channels

Neural Networks, 2022
The set-membership filtering is studied for a class of multi-rate sampling complex networks with communication capacity constraint. For reducing communication load, the weighted try-once-discard scheduling protocol is utilized to transmit the most needed measurement. To improve the filtering performance, a novel mixed compensation method is proposed to

Quantized set-membership filtering with communication constraints

2013 IEEE International Symposium on Industrial Electronics, 2013
This paper addresses the set-membership filtering problem with communication constraints for a class of discrete time-varying systems in the presence of unknown-but-bounded process and measurement noises. The dynamic coder and decoder are proposed to model the digital communication channel to transmit the error between the current measurement output ...

Set-Membership Filtering with Quadratic Inequality Constraints

2019 International Conference on Control, Automation and Information Sciences (ICCAIS), 2019
This paper investigates the problem of set-membership filtering for nonlinear dynamic systems with general nonconvex inhomogeneous quadratic inequality constraints. We propose an ellipsoidal state bounding estimation in the setting of unknown but bounded noise.

A nonlinear set‐membership filter for on‐line applications

International Journal of Robust and Nonlinear Control, 2003
AbstractA guaranteed estimator for a general class of nonlinear systems and on‐line usage is developed and analysed. This filter bounds the linearization error, then applies a linear set‐membership filter such that stability guarantees hold for nonlinear systems. A tight bound on the linearization error is found using interval analysis.
