Hydraulic system with PID control under photovoltaic panel supply using LabVIEW

Renewable and clean energy has always been a topic that people have paid attention to in the future. How to use renewable energy has become the current fashion topic. This paper introduces and simulates the current-voltage, power-voltage characteristic curves of solar cells under different radiations and different temperatures. This article not only analyses the characteristic curves of solar cells under different radiation and different temperatures, but also uses the maximum power point tracking method to determine the maximum power which is in the Standard Test Conditions (STC). The MPPT is used to generate power for the DC generator and to provide power to the hydraulic system. For hydraulic systems, the PID control system is used to precisely control the details of the hydraulic system. Based on the theory of the incremental conductance method, a new change was made in this article, so that the tracking effect of the maximum power point is better reflected in the power-time characteristic curve.
