Abstract

Enhancing the output power of the photo-voltaic (PV)
systems requires necessity to track the maximum power
point (MPP) robustly. The most techniques discussed in
many researches have played a role in obtaining MPP at
different conditions. Some of these techniques have some
drawbacks, one of which is the oscillation around the
operating point.
This thesis suggests sliding mode control (SMC)
technique to minimize and mend this problem. The strategy
of SMC is to design a sliding surface which set the
operating point. To reach this surface in finite time a
control law must be applied to the DC-DC converter gate.
The PV peak power can be obtained smoothly at different
conditions by changing the duty cycle of the converter gate.
The PV connected to the grid via seven level diode
clamped multilevel inverter (7-level DCMLI).
To prove the stability of the SMC, a comparison
between perturb and observe (P&O) and SMC methods was
done. Complete PV system was modeled and simulated
using MATLAB/SIMULINK. Moreover, experimental
prototype was implemented. The simulation and
experimental results are compared for clarification and
validation. These results agreed on that the SMC has low transient under sudden variation and reach the steady state
point faster than P&O. Moreover, they confirmed the
robustness, good performance of SMC strategy at different
environmental conditions.
