Formula for finding the sensitivity functions of linear electrical circuits in parts58_14.pdf

A formula for finding symbolic expressions of sensitivity of arbitrary linear electrical circuits in parts by dividing the circuit into subsystems is proposed. Electrical circuits can contain both bipolar elements and controlled sources (UIs) of voltage and current including ideal UIs – nullors. The scheme division is performed on the basis of an equivalent multidimensional generator (EMG) by the scheme-algebraic reduction method. The circuit sensitivity formula contains the sensitivity quotients of the EMG elements or their numerators, which are found using the difference circuit-algebraic sensitivity formula. The proposed formula excludes reducing multipliers and zero terms, and it requires to find the symbolic functions of relative sensitivity of the disclosure of a much smaller number of determinants of subcircuits-circuit minors than the known sensitivity formula based on bisection of determinants.

Electrical circuits, sensitivity, symbolic function, piecemeal analysis, circuit determinants, partial sensitivity, equivalent multidimensional generator, circuit minor.
