Real time performance comparison between PID and Fractional order PID controller in SMISD plant

This paper presents the comparative study between traditional PID controller with Fractional order PID (FOPID) controller to regulate the steam temperature in Single-Input Single-Output Small-Medium Industry Steam Distillation (SISO SMISD) plant at predetermined set point. Fractional order controller is designed based on the principle that the classical integer of /-term and D-term in PID controller can be generalize into non-integer order operation. The FOPID is consists of addition of 1 and p parameters in its algorithm compare to the traditional PID structure. Several fractional order applications which have been implemented in control engineering applications such as liquid level control, Autonomous Underwater Vehicle (AUV), nuclear reactor power, and many other. The controller's performance of the transient responses are evaluated based on the rise time, settling time and MSE index.
