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 PI^λD^μ controller, namely the coefficients K_P, K_I and K_D 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.
