چکیده

Abstract: A stepwise software sensor (SS) based on extended Kalman filter (EKF) is proposed. For monitoring scheme derivation, two methodologies concerning SS with a cascade structure and a novel formalization of kinetics are used. The Kalman’s filtering approach is applied for state and parameter estimation under assumption that the dry cell weight concentration is measured on-line only. The estimation algorithm is demonstrated using experimental data of fed-batch cultivation of a non-sporulating B. subtilis mutant realized in two compartment reactor as scale-down process simulator. The measurements obtained by new EKF-SS could improve the process monitoring and studying process dynamics.

A New Adaptive Extended Kalman Filter for a Class of Nonlinear Systems

This paper proposes a new adaptive extended Kalman filter (AEKF) for a class of nonlinear systems perturbed by noise which is not necessarily additive. The proposed filter is adaptive against the uncertainty in the process and measurement noise covariances. This is accomplished by deriving two recursive updating rules for the noise covariances, these rules are easy to implement and reduce the n...

Time Delay and Data Dropout Compensation in Networked Control Systems Using Extended Kalman Filter

In networked control systems, time delay and data dropout can degrade the performance of the control system and even destabilize the system. In the present paper, the Extended Kalman filter is employed to compensate the effects of time delay and data dropout in feedforward and feedback paths of networked control systems. In the proposed method, the extended Kalman filter is used as an observer ...

Tuning of Extended Kalman Filter using Self-adaptive Differential Evolution Algorithm for Sensorless Permanent Magnet Synchronous Motor Drive

In this paper, a novel method based on a combination of Extended Kalman Filter (EKF) with Self-adaptive Differential Evolution (SaDE) algorithm to estimate rotor position, speed and machine states for a Permanent Magnet Synchronous Motor (PMSM) is proposed. In the proposed method, as a first step SaDE algorithm is used to tune the noise covariance matrices of state noise and measurement noise i...
