11.11 CLOSED LOOP JOYSTICK – VEHICLE SPEED DEPENDENT CLOSED LOOP CONTROL
As each application is different, Danfoss has implemented a speed dependent closed loop control gain, configurable for
Closed Loop Joystick. When using a Closed Loop Joystick function, the PVED-CLS’s Closed Loop Joystick-control
algorithm can vary the closed loop gain, dependent on the vehicle speed.
The range is from 0 to 100 km/h for P3728 to P3729 and from 0 to 200 [%] for P3725 to P3727.
These parameters represent the three points on the figure 60 (Point A, B and C). The Auto-guidance-algorithm will make
linear interpolation in between each of the three points. It is allowed to move the three points in any direction, limited by
the following rules:
•
Point A is always specified at Vehicle speed = 0 km/h
•
The Vehicle speed has to increase for each point, hence “Vehicle speed” for Point A < “Vehicle speed” for Point
B and “Vehicle speed” for Point B < “Vehicle speed” for Point C.
•
Point C “Closed loop gain” is valid for Point C “Vehicle speed” and vehicle speeds above Point C “Vehicle
speed”
