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 ...

Discrete-Time Periodic Event-Triggered Distributed Set-Membership Estimation Over Sensor Networks

IEEE Transactions on Signal and Information Processing over Networks, 2021
This paper investigates the event-triggered distributed set-membership estimation problem over sensor networks. Firstly, a novel discrete-time periodic event-triggered mechanism (ETM) is originally proposed to decide when the sensor node transfers the ...

A Dynamic Event-Triggered Transmission Scheme for Distributed Set-Membership Estimation Over Wireless Sensor Networks

IEEE Transactions on Cybernetics, 2019
This paper is concerned with the distributed set-membership estimation for a discrete-time linear time-varying system over a resource-constrained wireless sensor network under the influence of unknown-but-bounded (UBB) process and measurement noise ...

Sets within sets: The influence of set membership on numerical estimates.

Journal of Experimental Psychology: Human Perception and Performance, 2014
Navigating the world requires attention to number; however, sets in real-world contexts are rarely homogeneous or presented in isolation, thus the task of determining what constitutes a relevant set for enumeration can be a difficult one. This contextual ambiguity increases the likelihood that irrelevant sets may bias our ability to accurately track ...

An Interpolatory Algorithm for Distributed Set Membership Estimation in Asynchronous Networks

IEEE Transactions on Automatic Control, 2022
This article addresses distributed estimation problems over asynchronous networks in a set membership framework. The agents in the network asynchronously collect and process measurements, communicate over a possibly time-varying and unbalanced directed ...

Power system set membership state estimation

2012 IEEE Power and Energy Society General Meeting, 2012
In this paper, a power system set membership state estimator (SMSE) in a bounded-error context is proposed based on interval constraint propagation. Its effectiveness is tested with the IEEE 4-bus, 14-bus, 30-bus, 118-bus, and 300-bus systems. Comparison is made between SMSE and typical existing methods. Simulation results show that the proposed method

Fault Detection for Satellite Reaction Wheel Based on Zonotopic Set-Membership Estimation

IEEE Transactions on Aerospace and Electronic Systems
A fault detection method is proposed based on zonotopic set-membership estimation to detect faults in the reaction wheel. First, considering the unknown but bound noise, a zonotope-based estimation is designed based on the nonlinear model of the reaction

Fault Detection for Brushless Direct-Current Motor Using Descriptor System-Based Set-Membership Estimation

IEEE Transactions on Control Systems Technology
Brushless direct-current (BLdc) motors are pivotal in electric vehicles, drones, and industrial systems due to their high efficiency and reliability. However, faults in stators, rotors, or inverters may degrade performance.
