The outstanding features of the theory are : 1. This paper is devoted to practical design execution, by means of a detailed 3×3 problem with large plant uncertainty, including open-loop instability and some non-minimum-phase plant elements. Some implementation issues are discussed.read more read lessĪbstract: A recent paper presented a quantitative synthesis theory based on Schauder's fixed point theorem, for uncertain multiple input-output feedback systems. An implementation by Eve Cohen has yielded encouraging preliminary results. This criterion ~s easily VlSUahzed m terms of a two-dimensional format for formulas. A procedure using the criterion of path acceptability for mattngs is discussed. General matmgs could be used as the basis for a variety of theorem-proving procedures, and there are many opportunmes for research m this area. ![]() ![]() It is shown that one may restrict quantifier duphcat,on to outermost quanUfiers without loss of completeness, though with possible loss of efficmncy. A complete exposition of the logical foundations of theorem proving via general matmgs is given, starting with proofs of appropriate versions of Herbrand's Theorem. Abstract: An approach to automaUc theorem proving using matmgs of arbitrary sentences is discussed No use is made of conjunctive normal form (clauses) or prenex normal form, since these forms tend to introduce superfluous redundancy, complicate the search for a proof, and impede analysis of the essential logical structure of the proposed theorem.
