Poles and Zeros of a transfer function are the frequencies for which the value of the denominator and numerator of transfer function becomes zero respectively. The values of the poles and the zeros of a system determine whether the system is stable, and how well the system performs.

How do you find the poles and zeros of a transfer function in Matlab?
First convert the poles and zeros to transfer function form, then call fvtool . Click the Pole/Zero Plot toolbar button, select Analysis > Pole/Zero Plot from the menu, or type the following code to see the plot. To use zplane for a system in transfer function form, supply row vector arguments.
What do you mean by poles in transfer function?
Zeros are defined as the roots of the polynomial of the numerator of a transfer function and. poles are defined as the roots of the denominator of a transfer function.
Can a transfer function have no zeros?
First-Order System
The transfer function has no finite zeros and a single pole located at s=−1τ in the complex plane. The reduced-order model of a DC motor with voltage input and angular velocity output (Example 1.4. 3) is described by the differential equation: τ˙ω(t)+ω(t)=Va(t).
