WebThis is known as bounded-input, bounded-output stability and is one of the main topics of this chapter. The stability of a feedback system is directly related to the location of the roots of the characteristic equation of the system transfer function. The Routh– Hurwitz method is introduced as a useful tool for assessing system stability.
