Reduced-order observer design using a Lagrangian method

This paper considers the problem of reduced-order observer design. A design procedure is proposed in which the impulse response of the observer is treated as the solution of a general optimization problem. Using principles from variational analysis, the corresponding Lagrangian system is reduced so as to yield observers of reduced-order. Using this approach, two different observer design problems are discussed and compared on an industrial example.
