Development and Validation of Control Systems with Variable Dead Time for Networked Control Systems

Abstract

Dead times can manifest in various control systems, posing a challenge due to their limiting effect on the maximum allowable gain required for system stability. Consequently, researchers have developed various structure-based controllers to enhance control performance or mitigate the strong influences of the dead time component. Among these structures are the Smith Predictor, Generalized Predictive Controller (GPC), and fractional PID controllers. With the significant advancements in networking and communication technology, the application of networked control has gained importance. However, due to the diverse network characteristics, additional variable delays are challenging to avoid. Modern control engineering offers methods capable of significantly improving control performance, considering both theoretical and practical aspects.
