  loop transfer
For n-by-n multivariable processes, multiloop controllers have n degrees of freedom and hence the n diagonal elements of closed-loop transfer functions can be designed to have desired closed-loop responses.
      
For MROC-based feedback loops, designed in order to achieve LQ optimal regulation, we characterize additive and multiplicative norm-bounded perturbations of the loop transfer function matrix which do not destabilize the closed-loop system.
      
State space conditions, formulated in an appropriate parameter space, define a convex set containing all the stabilizing control gains that guarantee an upper bound on the ?∞-norm of the closed-loop transfer function.
      
The controllers are designed in the operator space given the closed-loop transfer function.
      
The procedure to find the controller transfer function is reduced to algebraic division of polynomials and produces the dependence of the closed-loop transfer function on the roots of the characteristic polynomial of the closed-loop system.
