Abstract: This paper proposes a new fractional-order PID controller (FOPID) design based on the model reference adaptive control (MRAC) configuration using a practical numerical search method called moth-flame optimisation (MFO) algorithm for the parameters' adjustment. The five parameters of the fractional order PIλDμ controller, namely the coefficients KP, KI and KD and the fractional integral and derivative orders λ and μ are optimised by evaluating an exact quadratic performance index. Numerical simulation examples illustrate the effectiveness of the proposed tuning method for different plant model structures, and to show relative performance enhancement comparatively to other parameters' tuning strategies.
Keywords: moth-flame optimisation algorithm; fractional order PIλDμ controller; model reference adaptive control; MRAC; parameter tuning.
