This paper proposes a non-iterative computational algorithm for the design of fixed order controller for an H∞ optimization problem. Using the coprime factors and pole placement constraints, the fix-order controller design is reformulated as a convex optimization problem. The solutions are obtained using linear matrix inequality techniques. An aircraft model with 3-inputs and 3-outputs is used to illustrate the design algorithm.
