Open publisher page 10 citations

Abstract

To represent an iterative optimization technique for designing a fractional order PID (FOPID) controller based on a smith predictor (SP) is the main objective of this paper. Here, the long dead time compensating smith predictor based control scheme is proposed. Withal, the difficulty of using FOPID controller shoots up, as this controller hinges two extra terms i.e. derivative order and integral order. FOMCON toolbox with MATLAB/Simulink is used to aim a controller for a coupled tank system. Furthermore to show usability of FOPID, the results of fractional order controller based on the smith predictor (SP-FOPID) are compared with that of a PID controller based on the smith predictor (SP-PID) designed in a same way.
