AXIS#.OBS.KO
Description
AXIS#.OBS.KO sets the model gain of the velocity Observer.
This value represents the gain of the electro-mechanical plant of the system. The system has a high gain if it responds quickly and agilely, and this number will be high. For a heavily loaded system with a large inertia mismatch, the system does not respond quickly and is sluggish. This means the value of OBS.KO will be lower.
-
- It becomes important that OBS.KO is set correctly to ensure stability as the Observer's bandwidth (AXIS#.OBS.BW) is set lower.
The Observer is made up of a few components. Following is a block diagram of how the Observer is connected in the loops.
