Designing of the PID and FOPID controllers using conventional tuning techniques

This paper focuses on the designing of Integer order & fractional order PID controllers. Various tuning techniques are used for the designing of the PID controllers and the Fractional order PID controllers (FOPID). Ziggler Nicholas method, Cohencoon, Astrom-Hagglund (AMIGO), Chien-Hrones-Reswick methods are used to find proportional, derivative & integral parameters of PID & FOPID. Nelder Mead optimization technique is used to determine the specialized fractional order parameters for FOPID. The complete algorithm or the tuning process of each and every method has been explained and discussed. All the designs & their step response is specified & all the characteristics of the systems are discussed.
