A new approach to output feedback eigenstructure assignment by way of a bilinear transformation

The output feedback eigenstructure assignment problem is examined, and a new approach to computing the output feedback gain matrix is presented. A key advantage to this new approach is that the number of unknowns, which must be found such that a solution is obtained, is significantly reduced. Another advantage is that, since there is no subjective component introduced in the formulation of the design method which may inhibit or bias the results in some way, several, and in some cases all, solutions can be generated. These solutions may then be examined and candidate designs may be selected. It is proposed that, if coupled to an application specific expert system, the presented methodology can greatly reduce design time while providing superior designs. An example is given to illustrate the usefulness of the proposed method
