http://www-control.eng.cam.ac.uk/gv/p6/handout_nos4.pdf WebMar 29, 2024 · Such a linear system is called marginally stable. Let us consider another linear system with the transfer function G 2 ( s) = 4 s s 4 + 8 s 2 + 16 = 4 s ( s 2 + 4) 2 This system has repeated poles on the imaginary axis: s 1, 2 = ± 4 j and s 3, 4 = ± 4 j The natural response for this linear system is: y 2 ( t) = t sin 2 t which is unbounded.

Determining Stability using the Nyquist Plot - Erik Cheever

WebA marginally stable system may become unstable under certain circumstances, and may be perfectly stable under other circumstances. It is impossible to tell by inspection whether a … WebThe 'frequency response' interpretation of a Bode Plot only holds for stable (or marginally stable) systems. If you choose to draw it for an unstable system, then it does not have the usual physical interpretation. Specifically, it is NOT a frequency response (the steady-state amplitude and phase response to a sinusoidal input).
