Abstract

The use of servo/stepper motor actuators in solar tracker systems requires additional gear components. These additional components affect the movement response output of the solar tracker system. This study research the accuracy, response output of a single-axis solar tracker system using pneumatic actuators and ultraviolet (UV) sensors. The type of pneumatic actuator used is a double-acting cylinder. The pneumatic actuator functions to move the solar tracker mechanically and are connected directly to the solar panel frame. Solar tracker moves from east to west automatically and vice versa. The movement of the solar tracker angle from 0° to 45° based on the combined reading of 2 UV sensors (UVx and UVy). The direction of movement of the tracker is regulated through 4 digital valves which are operated digitally. While the tracker speed is regulated through 1 proportional valve which is operated continuously. The opening and closing of the digital valve and the size of the proportional valve opening are regulated based on the results of the data processing and signal conditioning on the microcontroller. The data processing method uses an adaptive neuro-fuzzy inference system (ANFIS). The ANFIS architecture uses a Sugeno fuzzy model with 2 inputs and 9 rules. Changes in the ANFIS output value are based on the combined reading feedback input from the UV sensor. System testing was carried out with a UV lamp. The experimental results show an average error of 1.6° for no-load conditions and 2.5° for loaded conditions in the east-west direction. The dynamic response of the system produces 2.08% overshoot, and 1.25% steady-state error.
