Abstract : The problem considered in the report was the synthesis of control laws when all states of a system could not be measured. The study was restricted to linear, deterministic, and time-invariant systems. The problem was solved by the design of observer systems to estimate a linear functional of the full-state feedback control. Three distinct algorithms for designing an observer were tested. The first was a direct solution of the observer design equations and involved setting as many gains as possible to unity. The second algorithm minimized a cost function which was related to the magnitudes of the gains associated with the observer system. The final algorithm was designed to minimize the effect of known errors in the basic state equations on the accuracy of the observer design. (Modified author abstract).
