Nonlinear Functional Observer Design for Robot Manipulators
Mathematics, 2023 In this paper, a nonlinear functional observer (NFO) is first proposed for the control design of robot manipulators under model uncertainties, external disturbances, and a lack of joint velocity information.

Secure event-triggered control of nonlinear networked systems via interval type-2 fuzzy observer design [PDF]
Scientific ReportsThis paper investigates the problem of observer-based event-triggered control for nonlinear networked control systems subject to deception attacks. An interval type-2 fuzzy logic was developed to improve the type-1 fuzzy form, which has a lower and upper

A Contribution in the Observer Design for a Class of Bilinear Singular Delayed Systems
IEEE Access, 2022 This paper proposes a functional observer for a bilinear singular systems with constant time delay present in both state and known input vectors. The considered system has transformed to an updated form in order to estimate both a state vector and an ...

A Note on Functional Observability [PDF]
IEEE Transactions on Automatic Control, 2016 In this note, we propose an alternative to characterize the functional observability for linear systems. The main feature is that we obtain a necessary and sufficient condition for the existence of a stable multi-functional observer of a time-invariant linear system.

Induction Motor PI Observer with Reduced-Order Integrating Unit
Energies, 2021 This article presents an innovative induction motor state observer designed to reconstruct magnetic fluxes and the angular speed of an induction motor for speed sensorless control system applications such as field-oriented control (FOC). This observer is

Functional Observability and the Design of Minimum Order Linear Functional Observers [PDF]
IEEE Transactions on Automatic Control, 2010 The design of a minimum-order linear functional observer for linear time-invariant systems has been an open problem for over four decades. This technical note provides a solution to this problem. The technical note also introduces the concept of Functional Observability/Detectability and shows that the well-known concept of Observability/Detectability ...

A Modified Functional Observer-Based EID Estimator for Unknown Continuous-Time Singular Systems
Applied Sciences, 2020 This paper presents the design of a linear quadratic analog tracker (LQAT) based on the observer–Kalman-filter identification (OKID) method and the design of a modified functional observer-based equivalent input disturbance (EID) estimator for unknown ...

Parametric design of reduced-order functional observers for linear time-varying delay systems
Measurement + Control, 2022 This paper investigates the design of reduced-order functional observer for linear time-invariant systems (LTI) with time-varying delay. Firstly, the sufficient condition for the existence of reduced-order delay-free functional observers is obtained ...

Observable Structure Functions [PDF]
Kybernetes, 1993 Considers the concept of structure function in reliability theory. Complete lattices are considered in order to model the space of performance levels for both system and components, leading to a general concept of structure function. Measurability with respect to the associate order topology is also assumed.
