Dual-zone control of the traction permanent magnet synchronous motor in the unmanned aerial vehicle

The study of the electric drive of unmanned aerial vehicles (UAVs) is relevant in connection with their use in many sectors of the civil industry. However, the study of new designs and controls for single-engine and multi-engine UAVs never stops, as more and more border regions begin to actively use them. The purpose of the modification is to improve the regulatory properties and reduce energy consumption for control. In this work, research, and development of a two-zone electric drive for an UAV of short and medium range, providing a flight range of up to 150 km and having a load capacity of up to 100 kg of a multi-engine type, were carried out. A potential approach for controlling the rotor speed of a permanent magnet synchronous motor (PMSM) was introduced. The study's findings are derived from two scenarios of electric drive operation: the nominal mode and the mode with an elevated rotor speed of the PMSM. Results were presented, indicating the efficiency of the algorithm under high-power conditions. The electric drive for the PMSM with two-zone control increased the speed of the PMSM rotor beyond the nominal value, with minimal losses, while also decreasing the power consumption of the UAV. Theoretical results are confirmed by simulation of a closed system in SimInTech.
