is the
frequency where the input signal is attenuated by 3dB (-3dB attenuation). The
phase shift between the output and the input is -45° at this frequency.
Precisely this cut-off frequency is called the bandwidth of a control loop.
Setpoint and disturbance behavior of a control loop
In this chapter you can read about:
Demand behavior .......................................................................................................... 198
Disturbance behavior ..................................................................................................... 198
Test functions ................................................................................................................ 198
Characteristics of a control loop setpoint response ........................................................ 199
The setpoint behavior is the behavior of the control loop for the setpoint variable W.
We assume that the disturbance variable Z=0.
The disturbance behavior describes the behavior of the control loop for disturbance
variable Z. In this case, we assume, in analogy to the setpoint behavior, that the
setpoint variable W=0.
