Development of a Matlab/Simulink Tool to Facilitate System Analysis and Simulation via the Adjoint and Covariance Methods

Abstract

The COVariance and ADjoint Analysis Tool (COVAD) is a specially designed software tool, written for the Matlab/Simulink environment, which allows the user the capability to carry out system analysis and simulation using the adjoint, covariance or Monte Carlo methods. This paper describes phase one of the COVAD evolution, which includes a user-friendly and flexible Graphical User Interface (GUI), a missile homing loop template, an adjoint construction module, a Monte Carlo simulation module and various analysis and plotting options. As an illustration, the application of the software to the preliminary analysis of a generic guided missile homing loop problem is included. The covariance analysis module is still under construction and will not be covered here. It is scheduled to appear in phase two of the COVAD development.
