How do you know if a transfer function is asymptotically stable?

▶ A transfer function is stable if its zero-input response converges to zero in the steady state regardless of initial conditions.

How do you find the stability of a system using transfer function?

Transfer function stability is solely determined by its denominator. The roots of a denominator are called poles. Poles located in the left half-plane are stable while poles located in the right half-plane are not stable.

How do you find the stability of a system using Z transform?

A system is stable if the absolute sum of its impulse response is finite: ch=∞∑n=−∞|h(n)|<∞

What is asymptotic stability in control system?

A system is said to be asymptotically stable if its response to any initial conditions decays to zero asymptotically in the steady state—that is, the response due to the initial conditions satisfies. (4.1)
