New Diagnosis and Fault-Tolerant Control Strategy for Photovoltaic System

چکیده
This paper discusses open-circuit fault (OCF) diagnosis and fault-tolerant control strategy (FTCS) of a nonisolated DC-DC converter. The photovoltaic power conversion structure (PPCS) consists generator an interleaved Boost converter (IBC). maximum point tracking (MPPT) the IBC ensures operation at power. design nonlinear Backstepping is detailed based on equivalent average model IBC, stability studied using Lyapunov’s theorem. proposed OCF detection sampling voltage across inductor much higher frequency than switching frequency. In situation occurrence high signal state, three negative samples condition for signaling presence fault; system continues its normal operation. simulation results show validity FTCS. improves performance in terms cost, reliability, service continuity.

Fault Tolerant Control Strategy for OmniKity-III
In this paper OmniKity-III (OK-III), a novel wheeled omni-directional mobile robot is developed and its kinematic model and control laws are derived. A special gear train was developed to have omnidirectional mechanism using conventional tire wheels. Several control laws are provided by considering the robot as a redundantly actuated wheeled mobile robot (WMR) on the plane. Since the robot has ...
متن کاملNew Strategies for Fault Tolerant Control and Fault Diagnostic
A recent architecture based on the Youla parameterization is analyzed for the nominal and uncertain case. This special architecture is characterized by a separation principle for the controller. In this paper, several stability results that allow to extend the structure to the integrated control/filter approach are presented. Two algorithms based on the recursive design and nesting of the integ...
