Active power management system for an unmanned aerial vehicle powered by solar cells, a fuel cell, and batteries
200W category, low-speed, long-endurance unmanned aerial vehicle (UAV) that employs solar cells, a fuel cell, and a battery pack as its power sources is considered. This study applies an energetic power management methodology that directs each individual supply to get the acceptable power, relying on the power provide and demand, rather than the passive method in that the ability sources irresponsibly generate power, relying on their characteristics. The power management system (PMS) underneath active management determines the facility output from every supply. The flight take a look at of the UAV with a PMS onboard is conducted for three.8 h. The active PMS verifies its own feasibility because it successfully keeps the facility sources within their correct operational bounds and maintains a target state-of-charge of forty fivepercent, while responding to the various conditions related to the ability needed. In addition, through a comparison of flight take a look at results with a power simulation of the passive technique, the usefulness, blessings, and downsides of an energetic power management methodology over a passive method are investigated.
