In this paper, we consider decentralized adaptive output-feedback stabilization problem for a class of large-scale time-delay nonlinear systems with unknown high-frequency-gain signs and with dynamic uncertainties. A memoryless decentralized adaptive output-feedback stabilizer is proposed, and global asymptotic stability results of the closed-loop system are established.
The adaptive control law, the noise estimator and the recursive adaptive parameter predicting algorithm are presented for a class of nonlinear discrete systems with multiple time delays based on dynamic approximate second-order increment full parameter recursive predicting model nonlinearization. They realize the adaptive control for the time-delayed nonlinear systems with larger time delays. The...
This paper presents an adaptive fuzzy tracking control scheme for SISO nonlinear time-delay systems. The scheme organically synthesizes adaptive control and Hinfin control. A kind of adaptive time-delay fuzzy logic systems is constructed and used to approximate the unknown time-delay functions. A Hinfin compensator is designed to eliminate fuzzy approximation errors and external disturbances. The...
