Design of Linear Residual Generators for Combined Fault Detection and Estimation in Nonlinear Systems
Sunjeev Venkateswaran, Costas Kravaris
A systematic method for the design of linear residual generators for combined fault detection and estimation in nonlinear systems is developed. The proposed residual generator is a…
On Functional Observability of Nonlinear Systems and the Design of Functional Observers with Assignable Error Dynamics
Costas Kravaris
This paper proposes a novel approach for designing functional observers for nonlinear systems, with linear error dynamics and assignable poles. Sufficient conditions for functional…
Disturbance decoupled functional observers for fault estimation in nonlinear systems
Sunjeev Venkateswaran, Costas Kravaris
This work deals with the problem of designing disturbance decupled observers for the estimation of a function of the states in nonlinear systems. Necessary and sufficient condition…
Functional observers with linear error dynamics for discrete-time nonlinear systems, with application to fault diagnosis
Sunjeev Venkateswaran, Benjamin A. Wilhite, Costas Kravaris
This work deals with the problem of designing observers for the estimation of a single function of the states for discrete-time nonlinear systems. Necessary and sufficient conditio…
Hidden Markov Model Based Approach for Diagnosing Cause of Alarm Signals
Joshiba Ariamuthu Venkidasalapathy, Costas Kravaris
When a fault occurs in a process, it slowly propagates within the system and affects the measurements triggering a sequence of alarms in the control room. The operators are require…
Functional Observers with Linear Error Dynamics for Nonlinear Systems
Costas Kravaris, Sunjeev Venkateswaran
In this work, the problem of designing observers for estimating a single nonlinear functional of the state is formulated for general nonlinear systems. Notions of functional observ…
