WIP, Description in progress
This part shows how to design dynamic outpur feedback control in mixed and sense for the continuous time.
Consider the discrete-time generalized LTI plant with minimal state-space realization
A continuous-time dynamic output feedback LTI controllerwith state-space realization
is to be designed to minimize the norm of the closed-loop transfer matrix from the exogenous
input to the performance output while ensuring the H∞ norm of the closed-loop
transfer matrix from the exogenous input to the performance output is less than ,

Given and , the matrices and can be found using a matrix decomposition, such as
a LU decomposition or a Cholesky decomposition.
If then it is often simplest to choose in order
to satisfy the equality constraint .
