Abstract
PID controller parameter stability limits are determined for processes with multiple lags. The limits are graphed in the gain-integral plane. Approximations to the PI limits are developed. This permits rapid estimation of the stable region. It is an approximate function of the maximum gain and the square root of the sum of the lags.
