LPRM: A user-friendly iteration-free combined Local Polynomial and Rational Method toolbox for measurements of multiple input systems[Formula presented]

Research output: Contribution to journalArticle

Abstract

This paper introduces a user-friendly estimation toolbox for (industrial) measurements of (vibro-acoustic) systems with multiple inputs. The vibration testing methods are very important because they help to improve the product quality and to avoid safety and comfort issues. The time-consuming testing procedures are nowadays fully substituted by techniques that evaluates the frequency response functions (FRFs). The toolbox provides a user-friendly nonparametric estimation method that uses a special combined Local Polynomial/Rational approach. The toolbox can be used even in case of multiple inputs with only one measured period — that would be not possible with the classical FRF estimator frameworks.
