This paper designs a dynamic positioning (DP) system with adaptive fuzzy controller. The Backstepping algorithm is employed as the adaptive law in the controller and a fuzzy system is used for approximating the disturbances and uncertainties. The proposed adaptive fuzzy controller is proven to be uniform bounded in the sense of Lyapunov. In simulation, the DP vessel will be more adaptive with environmental...
A kind of novel nonlinear adaptive control strategy is proposed for the general parameterized strict feedback uncertain nonlinear systems with unknown control directions. The proposed control scheme is based on the Backstepping algorithm and Nussbaum gain function. The uniformly asymptotical stability is proved by utilizing the augumented Lyapunov function. The simulation results on the course keeping...
Based on the system of Internet congestion control, an adaptive network controller is established as active queue management (AQM) algorithm to adjust the congestion marked possibility at the links, whose parameters is auto-tuned by applying the minimization of an integral criterion for adapting the change of the network. By comparing with those existent AQM schemes in the simulations, the adaptive...
