..Photovoltaic system with sliding mode control for work on for maximum power point

In this paper, a method for tracking maximum power in solar panels with the design of a networked photovoltaic system, including photovoltaic cell modeling, DC-DC choke converter design and sliding mode controller is presented. Simulations show that due to the existence of wires in the structure of the input / output structure of the chokes converter, its use to track maximum power points is superior to other methods. The maximum power point tracking has been implemented based on the chaos and observation algorithm in the photovoltaic system connected to the network and the control of the slip mode ring packet. The use of the sliding mode, according to the nonlinear nature of the system, can preserve the stability of the converter in a wide range of radiation, load and variations. In the presented slip mode, only the input voltage and capacitive filter flow are used as feedback and the design without the intervention of the converter model is completed. The efficiency of the proposed photovoltaic system has been evaluated using MATLAB / Simulink software.
