应该不是FOC,用单电阻采样没法满足高动态要求的。有空我再核实一下。可能加了同步整流。
这哥们的板画的真不错!羡慕!我就需要找个NB的硬件工程师,以前被那些画板的工程师搞怕了。
刚刚找到的:
Specifications for Version 3
PCB size: 34 x 25.6mm
PCB weight : 5.7 grams
Interfaces: USB, Serial, PWM, CAN
Input voltage range 6 to 42 volts (2-10S lipo)
Nominal max power 750 Watts continous, 1000W peak
Absolute max power 1500 watts
Nominal max current 40A
Absolute max current 50A
Features:
Active freewheeling------------------------------------------------------------------------------------------》同步整流
Live telemetry over CAN, USB or Serial
Real time current limiter
User configurable current limit----------------------------------------------------------------------------》FOC本来就是实时电流PI控制。
Control via CAN, PWM, USB or Serial
Closed loop RPM mode--------------------------------------------------------------------------------------》这个用FOC很容易做到,关键是反应太灵敏,减速时会回馈能量导致电压升高。
Servo mode (experimental)
Closed loop thrust mode (experimental)
8 to 64 KHZ switching rates
Improved error handling with AutoQuad flight controllers using CAN control
Improved logic side supply eliminates the need for external 5V supply
Speaker function
确定不是无感FOC. |
