Problems solved by technology
[0003] However, the existing UAVs have the following technical shortcomings: 1. Nowadays, most UAV oil-electric hybrid systems change the voltage output by controlling the engine speed. The voltage is proportional to the speed, and the engine speed cannot be adjusted accurately; Control the engine damper to control the engine speed, and the control error is large; 3. Some use DC-DC module to boost the voltage, which increases the weight of the drone and limits the carrying capacity of the drone

Description
technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic control system for a long-endurance unmanned aerial vehicle with an oil-electric hybrid power system. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", or "UAV" in English, is an unmanned aircraft that is controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by an on-board computer. Drones are often better suited for missions that are too "dumb, dirty or dangerous" than manned aircraft. According to the application field, UAV can be divided into military and civilian. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civilian use, drones + industry applications are the real rigid needs of drones; currently, they are used in aerial photography, agriculture, plant protectio...
