One of the problems which occur occasionally in designing a satisfactory controller for a deterministic controls systems is the need of the state variables which are not directly measurable. Luenberger proposed a scheme which approximately reconstructs inaccessible variables. No methods, however, are currently available for exactly reconstructing the missing variables from observable variables. In this paper a method is presented for exactly reconstructing the inaccessible variables. It uses measurable variables, their delayed values and the control variables on the maximum delay interval. As can be seen in Examples, the method may give satisfactory results in certain cases and can be easily implemented using a microprocessor.
