When Is a Short Audit Record Sufficient? An Audit-to-Decision Procedure for Industrial Compressed Air Systems

Short industrial compressed-air audits can contain thousands of samples while representing only a few dependent operating episodes. Autocorrelation therefore makes nominal sample count an unreliable basis for deciding whether a low-flow regime is sufficiently supported for an energy-efficiency or maintenance action. Th...

PID Tuning Approach Using Kolmogorov–Arnold Networks Under Varying Operational Conditions

This paper investigates the use of Kolmogorov–Arnold networks (KANs) for dynamic proportional-integral-derivative (PID) control tuning in first- and second-order linear systems under noisy conditions, time-varying reference trajectories, and varying plant parameters. Toy datasets, based on instantaneous system error, o...
