MRAC and FMRLC for a plant with time varying parameters

This paper presents a comparative analysis of two adaptive control methods used in case of time varying plant parameters. The first adaptive control method is based on the stability theory of Lyapunov and the other one is based on fuzzy logic. Also, the performances of the proposed control algorithms are evaluated with simulation environment. These control structures are designed for local compensation of the non-linear interactions and unknown payload variations in flexible-link gear drive
