Dual Luenberger observer design for linear systems

A parametric approach is proposed for the design of the dual Luenberger observers of linear systems. Based on a complete parametric solution to a class of generalized Sylvester matrix equations, parametric expressions for all the gain matrices of the observer are derived. The approach provides all the degrees of design freedom, which can be utilized to achieve some additional design requirements. An illustrative example also shows the design procedure of the proposed approach.
