## ( T r = I +Λ G ) ( I +Λ G ) ( B +G )

(10.5) which is another expression to represent the same idea introduced in the previous Chapters 5 to 8 (see Sec. 5-5.1) as,

In Eq. (10.7), the matrix C1 is the only part that depends on the nondiagonal parts of both the plant inverse B and the compensator bG . Hence, this matrix comprises the coupling, and from now on C1 represents the coupling
