TI TIDA－00916民用无人机电子速度控制(ESC)参考设计
TI公司的TIDA-00916是用于无人驾驶飞机电子速度控制(ESC)的无传感器高速磁场定向控制(FOC)参考设计,提供最好的FOC算法,以达到更长的飞行时间,更好的动态范围,更高的集成度,更小的板尺寸和更少的BOM元件.采用3颗LiPo电池速度高达12000RPM.主要用在无人驾驶飞机和UAV,高速马达和电池动力的电动工具.本文介绍了参考设计TIDA-00916主要特性,框图,无人驾驶飞机系统主要指标以及电路图和材料清单.
ESC modules are important subsystems for non-military drones and users demanding more efficient models that provide longer flight times and higher dynamic behavior with smoother and more stable performance. This design implements an Electronic Speed Controller (ESC) commonly used for unmanned aerial vehicles (UAV) or drones.
The speed control is done sensorless, and the motor has been tested up to 1.2 kHz electrical frequency (12kRPM with a 6 pole pair motor), using FOC speed control. Our high-speed sensorless-FOC reference design for Drone ESCs provides best-in-class FOC algorithm implementation to achieve longer flight time, better dynamic performance and higher integration, resulting smaller board size and fewer BOM components. Sensorless high speed FOC control using TI’s FAST™ software observer leveraging InstaSPIN-Motion™ C2000™ LaunchPad and DRV8305 BoosterPack.
