Unknown Input Observers for Biological Processes

This paper addresses the question of estimating unknown inputs in biological processes. The unknown inputs are either constant or periodic (as e.g. in municipal wastewater treatment plants where the loading rate is unknown yet of a period equal to one day). In particular the designed observer is able to recover the unknown periodic inputs over a few periods.

Designing SISO observers with unknown input

In this paper we investigate the observer design for Single-Input Single-Output (SISO) systems with unknown input. We find that the design conditions proposed by several authors in the past lead to unity relative degree of the plant and zeros of the plant in the open left half of the complex plane, for SISO systems. In other words an observer for a SISO plant with unknown input can be designed ...

Unknown input observers for singular systems designed by eigenstructure assignment

In this paper, any unknown input observers with orders between minimum and full orders can be established for singular systems by eigenstructure assignment method. The complete and parametric solutions for the observer matrices and for the generalized eigenvectors are obtained. The completeness and parametric forms of the solutions and the flexibility in selecting the observer order allow the d...

Passivity and Unknown Input Observers for Nonlinear Systems

The main objective of this work is to study the relationship between passivity and existence of UIO in the nonlinear case. This work is motivated by two facts: On the one side by the well-known relationship between passivity and robustness in control theory. On the other side the equivalence previously found by one of the authors in the linear (square) case between three concepts: existence of ...

402e Nonlinear Diagonal Unknown Input Observers for Fault Diagnosis

Pramod Vachhani, Sridharakumar Narasimhan, and Raghunathan Rengaswamy Process fault diagnosis is the problem of identifying the causal origins of faults in a process, given current sensor data and a priori knowledge about the process behaviour under normal and abnormal conditions. Fault diagnosis is increasingly becoming important for process safety, improved product quality and process economi...
