In this paper a brief account of the optimal tracking problem (O.T.P.) is given, to show that the response of the output vector of a linear observable system can be made to be close to some desired dynamic response. This optimal tracking problem has been applied to linear mathematical models of the F-100 jet engine for various operating conditions, and the results obtained prove that it is possible to achieve the desired thrust response at each operating condition without violating the engine's operational requirements. An attempt was made to establish whether a single control law, based on the solution of the optimal tracking problem at one condition, could be used with the engine throughout its operating range.
