WebApr 6, 2024 · As the response approaches 0 as time increases, the system is stable. Case 5 – Complex poles in the right half of the s-plane. Consider a complex pole pair at s = 2+3j and at s = 2-3j. The corresponding transfer function would be, By changing the transfer function in the previous script, we obtain the pole zero plot and impulse response as Webthe system is stable Therefore, the system is BIBO stable if and only if all poles of H(s) are in the left half plane of the s-plane. If you study CONTROL THEORY, you will learn more about this. Using feedback , you can build systems to steer the poles into the left half plane and thus stabilize the system. Here is an example of such a system.
