Marginally stable transfer function
Web(20 points) Are the following transfer functions stable, unstable or marginally stable? Explain your answers. You can use abs(x) in Matlab to find the to find the absolute value of x. z-.5 a. ... Since both poles have negative real parts, the system is stable. b. The transfer function Y(z) = (z - 1.2) / (z^2 + 1.9z + 0.9) can be written as Y(z ... WebOct 16, 2024 · Consider a classically configured closed loop control system (or amplifier) with a forward transfer function, a feedback transfer function and a summing junction. If this control system is in the theoretical state of being marginally stable then the loop gain is equal to exactly 1 and the loop phase is equal to exactly -360 degrees.

WebApr 14, 2024 · Since the poles of the transfer function \(G_{\text{RC}}(z)\) are located on the unit circle (see Fig. 4), the system is marginally stable. The gain at the fundamental frequency and at the integer multiples is theoretically infinite, as it is shown by the bode-plot depicted in Fig. 6. WebIt is a marginally stable system; also called the undamped system. Do you know, why? The reasons are: Poles are at the imaginary axis (real part is zero) From time response, it can be seen that oscillations are neither decaying nor growing. (It is also called sustained oscillations) Damping is zero
