Adaptive control algorithm of the RF-537 controller

摘要

Adaptive algorithm employed in the RF-537 industrial controller is presented. Objective is the same as in well-known Foxboro EXACT algorithm, i.e. by analyzing disturbance oscillatory responses, find the settings which yield specified damping and overshoot, simultaneously minintizing settling time. The algorithm gradually increases controller sensitivity proceeding along the line of constant damping. Root locus and simplex-like method are used.
