Operating conditions
Are characterised by numerical values for the individual variables that occur in a specific operating state of a system. The variables may change during operation (CETOP RP 100). As rule the operating
Band pass
Combination of high pass and low pass that is so designed that only signal frequencies in a defined frequency range (frequency pass) are allowed to pass largely unchanged; on the other hand elements o
Down time
Time from the "off" switching command to the "on" switching command (as a rule the same as the standstill time).
Hydraulic consumer
Represents in the function group for a hydraulic drive the component (cylinder, motor) in which the hydraulic energy is converted into mechanical energy.
Startup process
When a control system is started, the controlled variable is in principle still outside its control range such that in this range, in some circumstances, it is necessary to check the effect of the lim
Amplitude margin
Is the factor with which the static transfer factor of the open control circuit must be multiplied so that the related closed control circuit is at the stability boundary.
Power pack
Combination of various devices that carry out one or more functions.
Sampling feedback control
Controller with digital signal processing during which the continuous change in the controlled variable is sampled in steps. For the processing it is necessary to change to discrete time operation. If
