Tuning Control Loops: Nonlinearities and Anomalies
Control loops must be tuned during commissioning or as part of a preventive maintenance program to maximize efficiency, how equipment performs within the building system and ease of user control. This article explains how to remove and lessen nonlinear responses, which slows controller processing and dead time.Units: DualCitation: ASHRAE Journal, vol. 51, no. 6, June 2009
