Amillo-Gil, Jose M.2017-01-102017-01-101981http://hdl.handle.net/10919/74170Control systems governed by nonlinear neutral functional differential equations are formulated as abstract evolution equations in product spaces. At this point existence and uniqueness of solutions are studied. This formulation is used to develop a general approximation scheme for those systems. Convergence of this scheme is analyzed. It is also shown how spline based approximating methods fall within this general framework. An illustrative example is presented.iv, 88, [1] leavesapplication/pdfen-USIn CopyrightLD5655.V856 1981.A454Approximation theoryFunctional differential equationsDissertation
