Question

Routh Hurwitz criterion is used to determine

• A. Relative stability of the system.
• B. Time response of the system.
• C. Absolute stability of the system.
• D. Roots of characteristic equation graphically.

Hint:

Use the Routh Hurwitz criterion when determining the stability of higher-order systems, as it provides an easy method to check stability without calculating the poles directly.

Answer 1

The Correct Option is C

The Routh Hurwitz criterion is used to determine the absolute stability of the system. It provides a method to assess the stability of a system by examining the sign of the coefficients in the characteristic equation. If all the signs of the coefficients are positive, the system is absolutely stable.
