How do you get a pole-zero plot?
Zeros and Poles of Transfer Function
Use zplane to plot the poles and zeros of the transfer function. Visualize the zero-phase response of the filter. Overlay the unit circle and the pole and zero locations.
What does pole-zero plot tell us?
A pole-zero plot shows the location in the complex plane of the poles and zeros of the transfer function of a dynamic system, such as a controller, compensator, sensor, equalizer, filter, or communications channel.
How to plot pole-zero in matlab?
To create pole-zero maps with default options or to extract pole-zero data, use pzmap . h = pzplot( sys ) plots the poles and transmission zeros of the dynamic system model sys and returns the plot handle h to the plot. x and o indicates poles and zeros respectively.
How can you tell stability from pole-zero plot?
If all the poles lie in the left half of the s-plane, then the system is stable. If the system has two or more poles in the same location on the imaginary axis, then the system is unstable. If the system has one or more non-repeated poles on the imaginary axis, then the system is marginally stable.
