Understanding the Routh Hurwitz Criterion for Pole Placement in Control Systems

[Larrytsai]

Just want to confirm, The routh array DOES NOT tell you exact locations of poles, it only tells you whether or not you have poles on the left hand side of the s-plane or the right hand side.

Just want to confirm, The routh array DOES NOT tell you exact locations of poles, it only tells you whether or not you have poles on the left hand side of the s-plane or the right hand side.

I don't think it tells you whether you have poles in the right hand plane or in the the left hand plane. It tells you whether all poles are in the left hand plane or at least one pole is in the right hand plane or on the imaginary axis.
