Identification and Control of a Light System Using the Phase-locked Loop Technique

In this study, we propose the application of the Phase Locked Loop (PLL) technique to the control of light system. This one is destined to test the light effect on the evolution of the plants and the production improvement inside an agricultural greenhouse. In light control using PLL technique, the loop operates around a central frequency of which it departs very little, what permits to study it by the approach of continuous linear systems. We have developed the modelling of the PLL light control and presented a comparative analysis of the phase control system results gotten by the experience, the theory and the simulation. The Performances of achieved system have been also tested experimentally.
