H∞ Tracking Design of SISO Uncertain Nonlinear Fractional Order Time-Delay Systems: Adaptive Fuzzy Approach
In this paper, a fuzzy logic controller equipped with training algorithms is developed such that the H~ tracking performance should be satisfied for a model free nonlinear fractional order time delay system which is infinite dimensional in nature and time delay is a source of instability. The adaptive time delay fuzzy logic system is constructed to approximate the unknown time delay system functions and to deal with the linguistic uncertainties caused from delay terms. By using Lyapunov stability criterion incorporated with H tracking design technique, the free parameters of the adaptive fuzzy controller can be tuned on line by output feedback control law and adaptive law and the tracking error and external disturbance can be attenuated to arbitrary desired level. The simulation example is included to confirm validity and tracking performance of the advocated design methodology.
