7.3 PID Adjustment
Note: The adjustment here needs to use the log function, please insert the memory card
7.3.1 Adjust FF (Feedforward Compensation)
The specific parameters corresponding to the three axes are ATC_RAT_RLL_FF, ATC_RAT_PIT_FF,
ATC_RAT_YAW_FF; They are used to compensate for the slow response of the servo and the response
problem caused by the length of the connecting rod. It is generally greater than 0.22 for those with ailerons,
and generally less than 0.22 for those without ailerons. It can also be modified according to the actual test
1. First set the two axes of Roll and Pitch, set the corresponding ATC_RAT_RLL_FF and ATC_RAT_PIT_FF
to 0.15, and adjust the PID of the corresponding Roll and Pitch to the minimum first, as shown in the picture
below
After that, test the flight in Stabilized mode. Make some quick pitch and roll maneuvers, and then land.
Export logs, view logs, and open logs to view RATE.
