Summary: | The changes in the intensity of solar radiation cause the
electrical power produced by solar panels to be not optimal. The solar
panel position control system to the position of the solar is an effort to
overcome this problem. There are four Light Dependent Resistor (LDR)
sensors placed on the sides of the four cardinal directions. The difference
in the intensity of solar radiation received by each sensor causes the
position of the solar panel to turn perpendicular to the position of the solar.
The control method used is fuzzy logic control with three membership
functions. The controlled variables are pitch angle and yaw angle in an
active two-axis solar tracking system. Input fuzzy logic control is an error,
and output is PWM. The results of the performance of the pitch angle
control system produce settling time for 10 s and error steady-state
obtained by 0.080 %, while for the yaw angle control system produces
settling time for 13 s and steady-state error is obtained at 0.038 %. The
existence of a control system resulted in an increase in the percentage of
power above 30 % with a power difference of 7.49 W to a fixed panel. |
