介绍了一种基于FPGA的四轴飞行器无刷电机智能供电控制系统设计方案。设计以FPGA为系统的运算及控制核心,由太阳能充电单元、功率驱动单元、反电动势过零检测单元、电压采集单元、温度采集单元和锂聚合物电池等组成,完成在对四轴飞行器无刷电机智能供电及控制。系统测试结果表明本文所设计的智能充电系统功耗低、可靠性高、稳定性好。同时易于移植和调用。
A design scheme of intelligent power supply control system for four-axis aircraft brushless motor based on FPGA is introduced. It is composed of solar charge unit, power drive unit, back-EMF zero-crossing detection unit, voltage acquisition unit, temperature acquisition unit and lithium polymer battery, and so on, which is completed in the core of computing and control of FPGA. Motor intelligent power supply and control. The system test results show that the intelligent charging system designed in this paper has low power consumption, high reliability and good stability. At the same time easy to transplant and call.
