<p>An improved system for tuning process control equipment applies a load change of amplitude delta q to the process to effect a change in it and, therefore, in the controlled variable. Monitoring the response of the controller to that change, the system identifies an observed overshoot, OVSo, in the manipulated variable signal. From that overshoot signal and a predetermined theoretical overshoot signal, OVS tau , the system generates an optimum gain, Kopt, as a function of the mathematical expression <MATH> where, K is the current gain of the automatic control subsection, OVSo is the observed overshoot, and OVS tau is the predetermined overshoot.</p> |
