Question

Exercise 1 TF A marginally stable system has poles on the jo-axis. T F Asystem is stable if all poles lie in the right half-plane. TFIngeneral, a third-order system can be approximated by a second-order system's dominant roots if the real part of the dominant roots is greater than 1/10 of the real part of the third root. T F The s-plane plot of the poles and zeros graphically portrays the character of the natural response of a system T F The system sensitivity is the ratio of the change in the system transfer function to the change T F T F T F of a process transfer function for a small incremental change. A disturbance is a desired input signal that affects the system output signal The root of the characteristic function are the zeroes of the closed loop system A primary advantage of an open loop of a control system is the ability to reduce the system's sensibility The rise time is defined as the time required for the system to settle within a certain T F T F The transient response of a control system lasts for ever T F The gaim margin of a system is the increase in the system gain when the phase is -180° that percentage of imput amplitude will result in a marginally stable system.
