adaptation. The system passes on the output parameter as a valve command value to
the valve controller.
5.3.2 Cascading control structure
The control structure below is used in the HydraulicDrive:
Fig. 4: Overview of controller cascade structure
The cascade structure with the pressure and swivel angle controllers is called in
the "Pressure and swivel angle control" or "Pressure/flow control" operating modes.
The system offsets the swivel angle command value in swivel angle command value
processing with different variables. The outputs of swivel angle command value
processing and of the pressure controller are passed on to the switching logic. In
the switching logic, the system forms the swivel angle command value that is valid
for control. In actual pressure value acquisition, the system compares the different
actual pressure values and generates from them the resulting sign for the switching
logic. The output of the swivel angle controller is passed on to the manipulated
variable adjustment of the swivel angle controller.
