Nonlinear Control of Network based Systems with Random Time Delays using Intelligent Algorithms

ADAPTIVE FUZZY TRACKING CONTROL FOR A CLASS OF NONLINEAR SYSTEMS WITH UNKNOWN DISTRIBUTED TIME-VARYING DELAYS AND UNKNOWN CONTROL DIRECTIONS

In this paper, an adaptive fuzzy control scheme is proposed for a class of perturbed strict-feedback nonlinear systems with unknown discrete and distributed time-varying delays, and the proposed design method does not require a priori knowledge of the signs of the control gains.Based on the backstepping technique, the adaptive fuzzy controller is constructed. The main contributions of the paper...

H∞ filtering of network-based systems with random delays

The H∞ filtering problem is studied for a class of network-based systems with random network-induced delays in discrete-time domain. The considered random delay between the sensor and the filter may be longer than one sampling period and is modeled as a Markov chain. The filtering error system is modeled as a Markovian switched time-delay system and by using a properly constructed Lyapunov func...

Adaptive Dynamic Matrix Control for Network-based Control Systems with Random Delays

Random transfer delays in network-based control systems (NCSs) degrade the control performance and can even destabilize the control system. To address this problem, the adaptive dynamic matrix control (DMC) algorithm is proposed. The control algorithm is derived by applying the philosophy behind DMC to a discrete time-delay model. A method to estimate the network-induced delays is also presente...

Design of a Model Based Compensator for MIMO Systems with Time Delays and Constrained Inputs

Adaptive neural network control of nonlinear systems with unknown time delays

In this note, adaptive neural control is presented for a class of strict-feedback nonlinear systems with unknown time delays. Using appropriate Lyapunov–Krasovskii functionals, the uncertainties of unknown time delays are compensated for such that iterative backstepping design can be carried out. In addition, controller singularity problems are solved by using the integral Lyapunov function and...
