In this paper, the problem of adaptive tracking control is developed for a class of nonstrict-feedback switched nonlinear constrained systems. Backstepping technology combined with fuzzy logic systems (FLSs) are employed to estimate the unknown nonlinear functions of the switched constrained systems. By using the dynamic surface control (DSC) technology, the “explosion of complexity” can be reduced...
In this paper, a neural-network-based dynamic surface control method is developed for a class of non-strict-feedback stochastic nonlinear interconnected systems. Neural-networks (NNS) combined with adaptive backstepping technique are applied to model the unknown nonlinear functions of the stochastic interconnected system. The dynamic surface control (DSC) method is adopted to ensure the computation...
In order to solve the problem of introducing additional Total Degradation (TD) in adaptive satellite system caused by fixed High Power Amplifier (HPA) operating point, the paper proposes an adaptive HPA Input Back-Off (IBO) algorithm carried out on the gateway side in the Forward Link of the system based on Adaptive Coding and Modulation (ACM) techniques. On the other hand, the traditional way of...
This paper deals with the problem of adaptive fuzzy output feedback tracking control for a class of switched stochastic nonlinear lower-triangular systems without the measurements of the states. First, a reduced-order state observer is introduced to estimate the unmeasurable states of the switched stochastic system. Then fuzzy logic systems (FLSs) are employed to approximate the unknown nonlinearities...
