Frequency response function measurements in the presence of non-linear distortions. A general framework and practical advices

چکیده
In this paper we deal with the measurement of the frequency response function (FRF) of linear dynamic systems in the presence of non-linear distortions. The aim of this paper is to provide the reader insight in the impact of non-linear distortions on FRF measurements. It is shown how to measure the best linear approximation; how to detect, qualify and quantify the non-linear distortions, and this without using additional measurements. Finally, the use of the best linear approximation is illustrated. All results are experimentally verified.

A Generalized Linear Statistical Model Approach to Monitor Profiles
Statistical process control methods for monitoring processes with univariate ormultivariate measurements are used widely when the quality variables fit to known probabilitydistributions. Some processes, however, are better characterized by a profile or a function of qualityvariables. For each profile, it is assumed that a collection of data on the response variable along withthe values of the c...
متن کاملPractical common weights scalarizing function approach for efficiency analysis
A characteristic of Data Envelopment Analysis (DEA) is to allow individual decision making units (DMUs) to select the factor weights which are the most advantageous for them in calculating their efficiency scores. This flexibility in selecting the weights, on the other hand, deters the comparison among DMUs on a common base. For dealing with this difficulty and assessing all the DMUs on the sam...
متن کاملLinear Profile Monitoring in the Presence of Non-Normality and Autocorrelation
In an increasing number of practical situations, the quality of a process or product can be effectively characterized and summarized by a profile. A profile is usually a functional relationship between a response variable and one or more explanatory variables which can be modeled frequently using linear or nonlinear regression models. In this paper, we study the effect of non-normality on pro...
متن کاملExcitation design for FRF measurements in the presence of nonlinear distortions
In this paper, we discuss optimized strategies to measure the frequency response function in the presence of (nonlinear) distortions. To do so we will compare three classes of excitation signals. These signals will be used in an optimized measurement strategy, reducing the leakage effects to acceptable (user defined) levels, allowing to separate the disturbing noise influence from the impact of...
متن کاملStructural Damage Identification of Plate Structures based on Frequency Response Function and Natural Frequencies
In this paper, a structural damage identification method (SDIM) is developed for plate-like structures. This method is derived using dynamic equation of undamaged/damaged plate, in which local change in flexural rigidity is characterized utilizing a damage distribution function. The SDIM requires to modal data in the intact state and frequency response of damage state where most of vibration ba...
