Measurements
The next variables are located in the folder /driver.
powerf [W]
Actual power goes from the power supply.
energy [J]
Energy transferred since the last reboot. (The negative energy (e.g. regeneration) decreases the value. On the other hand, the accumulated absolute value can be found in /permanents/)
Filtering setup
To have meaningful measurements, the driver filters some of the readings. The amount of the filtering can be set using two parameters: kf and kr.
If a state variable's name ends with "f", it indicates that the presented reading has been filtered using the kf and kr settings. Example: /driver/motor/curentqf
kf [lpf]
Synchronous filtering gain for measurements (lpf). The higher the value, the more "trust" is assigned to the value averaged during the last electrical revolution.
kr [lpf]
Filtering gain for measurements (lpf). The higher the value, the more "trust" is assigned to the exponentially filtered value.
