Summary:In this paper, we discussed the fuzzy fractional and classical PI controllers for linear fractional systems subject to uncertain parameters. In our work, we have developed a fuzzy supervisor to adjust, online, the parameters of the fractional PI controller. Performance criteria such as response and rise times and the control sequence variance are analyzed for the proposed control structure and compared with those provided by classical PI controller. Disturbances are also added to the outputs of the chosen systems to test the capacity of the proposed controller in the face of these new situations. Besides the nominal model, two other operating points are considered where the system parameters change by an increase of 20% or a decrease with 20%. Simulation results are presented that show the efficiency of the fuzzy PI controller compared to conventional PI in terms of the response time at 5%, the rise time, and the control variance.
