We are looking to research if Gordon’s vector implementation would still be valid, or should we come up with completely new code for Path Manager zp 3.5, Assuming that the input comes from FreeRTOS queue, and show our approach.
Previous research we could refer, and possibly extend from:
Current Method
-Using vectors and way points
-The current vector implementation of the drone relies on ideal conditions for takeoff.
-Does not seem to use strong feedback loop to compare current position to goal, does not respond dynamically
PID Control Loop
We can better handle a changing environment if we add in some PID concepts into the implementation. We can adjust gradually the trajectories and get smoother acceleration and deceleration during takeoff or landing. This can also improve deviations, undershoots/overshoots. Given a set of waypoints assumed to be in a queue, we compare current position to the next waypoint. The error between the two position can be used to make corrective changes.
