Solution of the l/sub 1/ MIMO control problem without zero interpolation

The aim of this paper is to provide a new approach for the solution for the l/sub 1/ optimal control problem in the MIMO case which avoids zero interpolation in the numerical solution. While exact optimal solutions may not be computed, solutions which are arbitrarily close to optimal are obtained. Duality theory is utilized to provide converging upper and lower bounds for the optimal l/sub 1/ norm.
