Intelligent process monitoring by interfacing knowledge-based systems and multivariate statistical monitoring
(ELSEVIER SCI LTD, 2000-08)
An intelligent process monitoring and fault diagnosis environment has been developed by interfacing multivariate statistical process monitoring (MSPM) techniques and knowledge-based systems (KBS) for monitoring multivariable ...
Integration of multivariate SPM and FDD by parity space technique for a food pasteurization process
(PERGAMON-ELSEVIER SCIENCE LTD, 2001-03-15)
Multivariate statistical process monitoring (MSPM), contribution plots, and parity space fault diagnosis (FD) techniques are used to detect abnormal operation of dynamic processes and diagnose sensor and actuator faults. ...
A morphologically structured model for penicillin production
(JOHN WILEY & SONS INC, 2002-03-05)
A morphologically structured model is proposed to describe penicillin production in fed-batch cultivations. The model accounts for the effects of dissolved oxygen on cell growth and penicillin production and variations in ...
Intelligent real-time performance monitoring and quality prediction for batch/fed-batch cultivations
(ELSEVIER SCIENCE BV, 2004-02-19)
Supervision of batch bioprocess operations in real-time during the progress of a batch run offers many advantages over end-of-batch quality control. Multivariate statistical techniques such as multiway partial least squares ...
Real-time batch process supervision by integrated knowledge-based systems and multivariate statistical methods
(PERGAMON-ELSEVIER SCIENCE LTD, 2003-08)
Real-time supervision of batch operations during the progress of a batch run offers many advantages over end-of-batch quality control. Process monitoring, quality estimation, and fault diagnosis activities are automated ...
Batch process monitoring and its application to polymerization systems
(WILEY-V C H VERLAG GMBH, 2004-01)
Slight changes in raw material properties or operating conditions during critical periods of operation of batch and semi-batch polymerization reactors may have a strong influence on reaction mechanism and impact final ...
Online batch/fed-batch process performance monitoring, quality prediction, and variable-contribution analysis for diagnosis
(AMER CHEMICAL SOC, 2003-10-01)
An integrated online multivariate statistical process monitoring (MSPM), quality prediction, and fault diagnosis framework is developed for batch processes. Batch data from I batches, with J process variables measured at ...
Multivariable MPC system performance assessment, monitoring, and diagnosis
(ELSEVIER SCI LTD, 2004-03)
This study focuses on performance assessment and monitoring of model predictive control systems. A methodology is proposed to determine a benchmark and monitor model predictive control performance on-line. A performance ...
Feedback control of a continuous-flow stirred tank reactor with competing autocatalators
(AMER CHEMICAL SOC, 2003-08-06)
Two types of nonlinear feedback control schemes are introduced and analyzed for their capability of recovering the original state of an isothermal continuous-flow stirred tank reactor with one robust cubic autocatalytic ...
Statistical monitoring of multistage, multiphase batch processes
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2002-10)
The monitoring of intermediate phases of production is as important as monitoring and control of the final stage. Here a framework is proposed for monitoring overall process performance at the end of each batch.
