Derivation on Load Anticipation
LAder+limit %
Step: 0.1 %
Range: 0 – 100.0 %
Limit on Load step in + direction, changes bellow this limit will not generate any derivation
LAder-limit %
Step: 0.1 %
Range: 0 – 100.0 %
Limit on Load step in – direction, changes bellow this limit will not generate any derivation
LAder+ %
Step: 1 %
Range: 0 – 100.0 %
Amount of derivation when Load increases
LAder- %
Step: 1 %
Range: 0 – 100.0 %
Amount of derivation when Load decreases
LAder+recover %
Step: 0.01 %
Range: 1.01 – 10.00 %
Derivation curve definition – drop from + value. Initial value is divided by this number repeatedly once
per 0.1s. So higher value means faster drop to zero.
LAder-recover %
Step: 0.01 %
Range: 1.01 – 10.00 %
Derivation curve definition – drop from - value. Initial value is divided by this number repeatedly once
per 0.1s. So higher value means faster drop to zero.
When Load is suddenly changed, there is positive influence if throttle is opened or closed for short
period of time. To do that there is derivation on Load and result is added to PID output. There is Limit
to avoid jitter based on noise on power signal. If load changes are less then this limit, no derivation is
generated.
Function works as follows
