Relation (formula) between a gain and proportional band

WebThe transfer function of a PID controller is found by taking the Laplace transform of Equation (1). (2) where = proportional gain, = integral gain, and = derivative gain. We can define a PID controller in MATLAB using a transfer function model directly, for example: Kp = 1; Ki = 1; Kd = 1; s = tf ( 's' ); C = Kp + Ki/s + Kd*s. WebProportional Band Some manufacturers use different forms for the same tuning parameter. The popular alternative to Kc found in the marketplace is proportional band, PB. ... When CO and PV have units of percent and both range from 0% to 100%, the much published conversion between controller gain and proportional band results: PB = 100/Kc. sand looking things in slippers
