Routh array marginally stable

WebTo have a stable system, each element in the left column of the Routh array must be positive. Element b1 will be positive if Kc > 7.41/0.588 = 12.6. Similarly, c1 will be positive if Kc > -1. Thus, we conclude that the system will be stable if -1 < Kc < 12.6 This example illustrates that stability limits for controller parameters can be derived WebFeb 24, 2012 · 2) Part two (sufficient condition for stability of the system): Let us first construct routh array.

Chapter 6. STABILITY

In control system theory, the Routh–Hurwitz stability criterion is a mathematical test that is a necessary and sufficient condition for the stability of a linear time-invariant (LTI) dynamical system or control system. A stable system is one whose output signal is bounded; the position, velocity or energy do not increase to infinity as time goes on.
