Single Lag
Applets
Exercise
- Go to the Single Lag Frequency Response and choose values for gain and
time constant.
- Vary the value of the frequency and hence plot the Bode Diagram.
- Check your answer by looking at the Single Lag Bode Diagram.
- Now look at how the Frequency Response changes for different process
parameters.
- Finally go to the Bode Diagram and see the effect of
varying the gain and time constant.
Questions
- What is the significance of the Amplitude Ratio at Zero Frequency?
- What is the maximum (negative) value of the Phase Angle?
- What is the effect of the time constant on the Phase Angle?
