An Interactive Program for the Calculation and Analysis of the Parameter Sensitivities in a Linear, Time-Invariant System.

Abstract

In this paper, a new algorithm is developed to calculate the output 'sensitivity matrix' of a linear, time-invariant, single-input single-output control system with piecewise constant input and output measurements taken at constant time intervals. The algorithm incorporates the singular value decomposition to investigate parameter identifiability and estimation accuracy in relation to the system as a whole and in relation to the model of the system. As a result, a structural condition on identifiability is imposed; and the system designer now has a tool to evaluate how well the model describes the system. The algorithm is verified by checking its results with those using a standard software package for numerical integration. It is then used to investigate input and structural design issues. (Author)
