Presence of nonlinear factors, such as stiction, hysteresis, and deadband, in a control valve
imposes limitations on the performance of the control loop. The importance of assessing the …

The paper presents results of the observations on behavior and properties of the control
quality that is met in real industrial practice. The analysis is based on data from several …

Assessing the quality of industrial control loops is an important auditing task for the control
engineer. However, there are complications when considering the ubiquitous nonlinearities …

This paper presents review and comparison of alternative methodologies for control
performance assessment. The approach uses nonlinear time series analysis, such as non …

Valve stiction is the most common root of oscillation faults in process control systems, and it
can cause the severe deterioration of control performance and system instability, ultimately …

Assessing the quality of existing industrial control loops, or comparing between two
alternative controller designs is becoming an important routine auditing task for the control …

The performance of the pilot solenoid valve (PSV) has a significant impact on the efficiency
and service life of an automatic transmission (AT) in automobiles, and it is very difficult to …

Damage modeling and life extending control for steam turbine are studied in this work.
Taking the rolling process of a 300 MW steam turbine unit as an example, this paper …

Control performance monitoring has attracted great attention in both academia and industry
over the past two decades. However, most research efforts have been devoted to the …

To reduce the effort and cost of model maintenance in model predictive control (MPC)
systems, this paper explored a model deficiency diagnosis and improvement method by the …
