In the process industry, it is crucial to ensure safety, high product quality, strict environmental
compliance, and optimum economics. Among other important factors, this calls for high …

Valve stiction is one of the most important failure modes of valve, which may make the
control loops suffered from severe performance degradation. Therefore, valve failure …

A common source of poor control performance in industrial processes is represented by
stiction in control valves, which often induces offset, oscillating behavior, and even loss of …

The extensive existence of governor deadband has a significant influence on the minimum
frequency of power system after a disturbance. However, the strong nonlinearity of …

A comparative study of different models and identification techniques applied to the
quantification of valve stiction in industrial control loops is presented in this paper, with the …

The detection and diagnosis of oscillation are of great importance to maintain the control
performance of the process plant. Even though some algorithms based on time-frequency …

The status of control valves directly influences the routine operation of industrial process.
Stiction nonlinearity is one of the widely known failure modes of a valve, which may hazard …
