Release Information
Version 5.3 (20191004-112306)
This has the effect of causing the RUN_USING_ENCODERS and RUN_TO_POSITION modes to use
PIDF vs PID closed loop control on these motors. This should provide more responsive, yet stable, speed control.
PIDF adds Feedforward control to the basic PID control loop.
Feedforward is useful when controlling a motor's speed because it "anticipates" how much the control voltage
must change to achieve a new speed set-point, rather than requiring the integrated error to change sufficiently.
The PIDF values were chosen to provide responsive, yet stable, speed control on a lightly loaded motor.
The more heavily a motor is loaded (drag or friction), the more noticable the PIDF improvement will be.
