Abstract
An identification technique that includes a closed loop parameter estimation algorithm for process gain, time constant and deadtime. The estimation algorithm uses time integrals of system variables responding to a step input. Proper selection of the integrals (control areas) results in a set of equations which are solvable for desired process parameters.
