AbstractNon‐linear equations havingmultipleSolutions are usually associated with sharp turning points in the associated solution curves. Existing solution methods often fail or become extremely slow in the neighbourhood of such turning points. This paper presents an efficient algorithm based on thebackward‐differentiation formula(BDF) which overcomes this problem.For the special subclass of non‐linearseries‐parallelcircuits, this algorithm is generalized to allowallbranches ofdriving‐pointandtransfer characteristicsto be traced efficiently. For anyfixedvalue of thedriving‐pointvoltage or current source, this algorithm guarantees thatallsolution

摘要:

AbstractThis paper presents a topologically based theoretical background for designing tests for identification of faulty parameter values in linear subnetworks. Nodal voltages are assumed t o be obtainable either by measurements or, indirectly, as a result of a nodal fault analysis. A formulation of nodal fault analysis for subnetworks is presented. It is shown how this approach can be used to evaluate faulty elements within inaccessible faulty subnetworks. The objective of this work is the reduction of the number of required current excitations and, thereby, the number of voltage measurements. The Coates flow‐graph representation of a network is use

摘要:

AbstractA previously defined sensitivity measure for state‐space realizations is used, and the attainable minimum value and its necessary and sufficient conditions are given. An explicit optimization procedure which evaluates the complete class of realizations with minimum sensitivity is proposed. Conditions for minimizing the sensitivity under an 1, dynamic range constraint are established and an explicit method for obtaining this minimum is given. Since the relation between this sensitivity measure and the noise power gain for I, scaled digital filters can be given, and since the main part of the optimization can be carried out without taking into account the dynamic range constraint, a simple procedure for simultaneous minimization of sensitivity and round‐off noise is obtained. A numerical example is given to exemplify the computational proced
