this paper addresses a nonlinear observer based control scheme to synchronize chaotic systems subject to uncertainties and external disturbances. it is assumed that the dynamic of slave system is not completely known. in order to compensate for the system perturbation resulting from parameter variations and mismodeling phenomena, an adaptive neural network observer is employed to handle this pr...

This paper addresses the problem of H∞ fuzzy observer-based non-PDC controller design for uncertain T-S fuzzy systems with external disturbances. The synthesis of the observer-based controller is based on a fuzzy Lyapunov function and the descriptor redundancy approach. Moreover, the design is extended for the problem with control constraint. The observer and controller gains are obtained by so...

In this paper, a novel adaptive Takagi-Sugeno (TS) fuzzy observer-based controller is proposed. The closed-loop stability and the boundedness of all the signals are proven by Lyapunov stability analysis. The proposed controller is applied to a flexible-transmission experimental setup. The performance for constant payload in the presence of noisy measurements is compared to a controller based on...

Combustion engine control depends strongly on the availability and the quality of the signals involving in the controller construction. In general, not all signals are available through measurement, and therefore an observer is necessary to realize the controller. This paper proposes an observer design for a combustion engine test bench. The observer is used to estimate the torque and the rotat...

A biplane quadrotor (hybrid vehicle) benefits from rotary-wing and fixed-wing structures. We design a dual observer-based autonomous trajectory tracking controller for the quadrotor. Extended state observer (ESO) is designed estimation, based on this Backstepping (BSC), Integral Terminal Sliding Mode Controller (ITSMC), Hybrid (HC) that combination of ITSMC + BSC are tracking. Further, Nonlinea...

This paper proposes a stabilizing controller for single machine power system with nonzero conductance of transmission line. The proposed controller uses a reduced order observer to estimate the power angle of the system. The stability of the reduced order observer and that of the closed loop system incorporating the observer based stabilizer are given based on Lyapunov direct method. Simulation...

Symbolic control is an approach to the of continuous or hybrid systems with specifications expressed in a logic form. This based on use symbolic models describing dynamical system behavior finite description transition relation between its states. In literature, many results using this assume availability full and exact information about states compute actions. letter, we consider more realisti...

A robust control scheme is proposed for a class of systems with uncertainty and time delay based on disturbance observer technique. A disturbance observer is developed to estimate the disturbance generated by an exogenous system, and the design parameter of the disturbance observer is determined by solving linear matrix inequalities (LMIs). Based on the output of the disturbance observer, a rob...
