Abstract :
A synthesis procedure is developed which yields an optimal 2-D compensator realization that minimizes the output noise power, subject to a scaling condition on the state variables to avoid overflow. The output noise power and the scaling condition are related to two positive definite matrices. Using these matrices, the second-order modes of the compensator are obtained and used to minimize the output noise power
