LMI-based Luenberger observer design for uncertain nonlinear systems with external disturbances and time-delays

Nonlinear Observer-based Chaos Control for SPMSM with Both Uncertain Parameters and External Disturbances

This paper proposed a robust chaos control scheme for surface permanent magnet synchronous motor (SPMSM) drive system considering the uncertain parameters and external disturbances. A nonlinear time delay estimator is utilized to estimate the nonlinearities, uncertain parameters and disturbances of the system on line, so it is not necessarily required the exact model of the system. Then, based ...

Observer-Based H∞ Control for Stochastic Systems with Delays and Nonlinear Perturbations: LMI Approach ?

This paper considers the problem of observer-based H∞ control for a class of Itôtype stochastic delay systems with nonlinear perturbations. An observer-based controller is constructed based on Lyapunov-Krasovskii approach, which guarantees the closed-loop system is robustly stochastically asymptotically stable in the mean square with prescribed H∞ disturbance attenuation level for all admissibl...

Observer-Based Mixed H2/H∞ Control Design for Linear Systems with Time-Varying Delays: An LMI Approach 1 Observer-Based Mixed H2/H∞ Control Design for Linear Systems with Time-Varying Delays: An LMI Approach

Abstract: This paper presents a convex optimization method for observer-based mixed H2/H∞ control design of linear systems with time-varying state, input and output delays. Delaydependent sufficient conditions for the design of a desired observer-based control are given in terms of linear matrix inequalities (LMIs). An observer-based controller which guarantees asymptotic stability and a mixed ...
