Please consider the following closed-loop Multiple-Input Multiple-Output (MIMO) control system:
R₁(s) and R2(s) are the reference signals (or inputs),
•
G₁(s) (where i = 1,2,3,4,5) are the plant transfer functions,
•
C₁(s) and C2(s) are the responses (or system outputs),
•
All of them are in Laplace domain.
