The analog controllers have a wide range of applications in industrial control. The fifth order model of superheated steam temperature system is taken for study. Most –τs of the tuning algorithms are based on FOPTD models which is given by G(s) = Ke /(Ts+1). If the plant is not approximated well to FOPTD model, good controllers may not be designed using existing algorithms. Genetic algorithm is a stochastic algorithm based on principles of natural selection and genetics. To tune the analog controllers using genetic algorithm, it does not require any FOPTD model. Hence the analog controllers P, PI and PID are tuned using genetic algorithm for superheated steam temperature system and the results are compared.
