Comparative analysis of different fractional PID tuning methods for the first order system

This paper deals with the use of fractional order PID (FOPID) controller for controlling the output response of first order systems. In this paper, the PID controller and FOPID controller has been tuned using various optimization techniques: fminsearch, fmincon, genetic and fuzzy. The simulation result shows that the FOPID controller performs better than PID controller in most cases.
