Abstract : For a given nonlinear system, consider the design of a nonlinear control law such that the following properties hold. First, as in the extended linearization method, linearizations of the closed-loop system about constant operating points of the closed-loop system achieve specified, linear design objectives. Second, the Taylor series expansion of the closed-loop state equation about any constant operating point is such that terms of order 2, 3..., k are zero. or at least are minimized in a certain sense. Conditions under which this can be achieved, while simple to state, are restrictive. Keywords: Nonlinear Control Systems; Control Theory.
