Sensitivities by the state variable approach

Abstract

The well-known procedures for calculating transient-re sponse sensitivities, frequency-response sensitivities, and pole sensitivities have been successfully and profitably applied for several years. However, the usual formulations are not well suited for analysis of large systems on modern analog or digital computers. Expressions for these sensitivi ties are developed in this paper using simple matrix ma nipulations (usually referred to as the state variable ap proach). The state variable formulation illustrates clearly the structure of the sensitivity equations and provides an efficient procedure for computer calculations.
