Dual-axis directing for photovoltaic module using PID control

The configuration of a PID controller is presented in this paper on the example of a positioning system for a prototype measurement station with photovoltaic system and dual-axis directing. Since the prototype measurement station is supposed to be used for research possibilities of electrical energy production using photovoltaic modules, and based on the conventional Liu-Jordan-Klein analytical model, the whole nomenclature is adjusted to the selected model. For the described prototype measurement station the PID controller for azimuth positioning was programmed, parameterized and run in test mode, after which the same procedure was provided for slope positioning. Such PID controllers can be used simultaneously.
