Fractional order fuzzy backstepping torque control of electrical load simulator

A novel Fractional order adaptive robust control is proposed for electrical load simulator system (ELS) using fuzzy back stepping method. A fractional order linear sliding surface is constructed and a robust fractional order control law is derived using back stepping method. The control performance of load simulator is affected by extra torque disturbance. Fuzzy logic system is used to estimate extra torque disturbance. A fractional order adaptive law is derived to update fuzzy logic system using Lyapunov theorem. The effectiveness of proposed control scheme is verified using numerical simulations.
