Time-delay processes are frequently found in industry and the most common representation is a first order plus delay time (FOPDT) transfer function. The identification of time delay systems is a challenging task. Usually, the process has to be disturbed in order to excite enough the system to provide the information for identification. This work presents a genetic algorithm to identify the system using closed loop information. Therefore, a setpoint change in the reference is used, avoiding disturbances to the process.
