Posicionador de painel fotovoltaico automático

Abstract

The project deals with the development of a prototype of positioner for photovoltaic module with two degrees of freedom with only one source of torque, so that the axis of the actuator used is directly coupled to the mechanism of 4 bars responsible for the variation of the elevation of the prototype and the transmission of this movement to the azimuth axis, which is performed through a set of gears. The mechanical system is controlled by a reconfigurable input and output device, MyRIO, and the programming of this controller is developed in LabVIEW Software. The system loop is closed by an accelerometer used as an inclinometer which, therefore, feeds the system with the elevation angle of the module. The implemented control is done by a PID controller. Finally, it is intended to prove the feasibility of the system by comparing its energy generation acquisitions with those of a fixed photovoltaic module.
