FOC Motor Control

  • Kevin McAndrew
I am currently using standard Brushless DC (BLDC) control which uses a 6 step method of controlling the motor. However, there is a different method of control called Field Oriented Control (FOC) which is more efficient and gives maximum torque.

Building a Wheel

Web Interface Working

  • Kevin McAndrew
Flight test report Tuesday 1.9.2020 11:26 Positives: New access point web interface worked very well All parameters worked It wasn’t wet :D Airspeed works and appears to be altitude agnostic (shortlived flights don’t give good data) Negatives: The plane kept leaning left Integral barely helped any leaning Integrated while in my hand Plane seems to be balanced (at least very roughly) The plane either nose-dived or stalled Oscillation occured during flights Gusts of wind caused plane to go out of control Summary The actual web interface for the plane is working very very well.
