Abstract:

This paper is devoted to proposing a simple method to tune the parameters of a fractional order PI (FOPI) controller. The studied control scheme is a fractional filtered Smith predictor (FFSP) structure, which can compensate for the inherently long dead time of the industrial processes. The proposed frequency domain scheme would be a practical approach to compensate the stable processes, which can be modeled by a fractional order counterpart of First Order Plus Dead Time (FOPDT) transfer function. Two fractional order filters are also used to improve the reference tracking and to enhance the robustness of the compensated system. The obtained results of practical implementation on a pressure plant and the comparison results are given to demonstrate the effectiveness of the proposed technique.
