I am working on a project where i am trying to decouple the internal interaction of 2x2 industrial plant transfer function matrix aiming to get diagonal dominant matrix (Q(s)= G(s)K(s) where G(s) is the plant transfer function matrix and K(s) is the calculated compensators matrix) . I am getting 4 second and first order compensators each with a pole located in the right hand side of the s-plane. Can I acknowledge such compensators? Will the pole located in the RHS of s-plane be a potential of troubles or difficulties for controlling the resulted decoupled transfer function matrix Q(s)?
Thank you in advance
