A Novel Method to Prevent Control SystemInstability Based on a Soft ComputingKnowledge System

摘要

The aim of this study is to present a novel soft computing method to as-sure PID tuning parameters place the system into a stable region by applying thegain scheduling method. First the system is identified for each significant opera-tion point. Then using transfer functions solid structures of stability are calculatedto program artificial neural networks, whose object is to prevent system from tran-sitioning to instability. The method is verified empirically under a data set ob-tained by a pilot plant.
