Time Response of Second Order Transfer Function and Stability Analysis

WebIf a solution does not have either of these properties, it is called unstable. For example, the solution y = ce-x of the equation y ′ = - y is asymptotically stable, because the difference of any two solutions c1e-x and c2e-x is ( c1 - c2) e-x, which always approaches zero as x … Web1 Answer Sorted by: 1 If G ( s) is an arbitrary transfer function it is BIBO stable if and only if it is linearly stable. The proof is simple. Let x ( t) be a bounded input and put x 0 as the least-upper-bound of x ( t). The Laplace transform gives x 0 s > X ( s) hence G ( s) x 0 s > G ( s) X ( s) hence
