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...

The Generalized Predictive Controller (GPC) [1], [2] belongs to the general class of predictive controllers. The authors have proposed an alternative (although equivalent) formulation for the GPC in state space [7]. This formulation is based on a robust observer [5], and the poles selection is closely related to the controller robustness. An important feature of predictive controllers consists ...

In an electrolytic capacitor-less inverter, source current harmonics are caused by LC-circuit resonance, and the power factor deteriorates. Therefore, inverter must reduce control without additional circuits. This paper proposes a method to in three-phase of permanent magnet synchronous motor drive. The proposed consists using full-state feedbacks LC-resonance state observer. validity is confir...

This paper presents a novel observer-based robust fault predictive control (OBRFPC) approach for wind turbine time-delay system subject to constraints, actuator/sensor faults, and external disturbances. The proposed is based on an augmented state-space representation that contains variables estimation errors. then used synthesize controller. In addition, observer developed estimate both state f...
