微飞行器用无刷直流电动机驱动控制系统

The Driving Control System of Micro Brushless DC Motor Used in Micro Craft

作为多旋翼微直升机的驱动器,微型无刷直流电动机具有结构简单、制造方便、无换向火花等特点。文章根据微型飞行器的系统需求,设计并完成了一套可以实现旋翼驱动和上层计算机参数设置和控制的测试系统。该系统包括驱动、控制、通信、计算和反馈五部分,并基于DSP芯片TMS320LF2407。

As the driver of the micro multi -rotor craft, the micro BLDC motor was of simple structure,easy fabrication , non commutation spark and so on. According the need of micro craft, a test system was presented which can implement the driving of rotor, set parameters and testing. It included five parts of driving, control, communication, computation and feedback based on DSP chip TMS320LF2407.
