Method of Tuning Proportional Band for Arbitrary Settling Time

Abstract

This paper presents a method of tuning the proportional band for an arbitrary settling time without overshoot. The materials and human resources management in a factory can be optimized according to the settling time. A temperature controller is widely used in the manufacture of industrial machinery. In general, a temperature-controlled system has a large time constant and dead time. Getting the output close to a set point at an arbitrary settling time is difficult. The proposed method optimizes the proportional band and PID parameter based on the step response of first order plus dead time by using the settling time. The proposed method can be extended to uniform heating and peak power suppression control. Simulation and experimental results showed that the proposed method is effective for a temperature-controlled system.
