| Popis: | The problem of sensor fault tolerant control of a DC-DC buck converter for voltage regulation of a photovoltaic (PV) system is considered in this paper. By the mean of hybrid dynamical system approach (HDS); a new hybrid PV model is proposed in order to deal with the non-linearity of the PV mathematical model, the stability of the hybrid observer and the closed loop of the system is demonstrated by means of Lyapunov analysis. The simulation was performed using real PV array parameters that were obtained using Particle Swarm Optimization (PSO) identification algorithm. |
