Abstract
This paper concentrates on the modeling and control of an autonomous photovoltaic
power electricity generation system.
The system consists of a PV cell, a DC DC Buck boost converter used for Maximum Power Point Tracking (MPPT). As a
consequence, the PV cell itself cannot maintain a constant DC voltage and function as a DC voltage power supply source.
To overcome this problem, a DC DC converter with the nonlinear control sch eme, sliding mode control (SMC) may be used.
The DC/DC Buck boost converter controlled by using the sliding mode approach is used for tracking the maximum power
point MPP. The proposed controller is ro bust to environment changes, load variations and it can be implemented effectively
and economically..
