Industrial robots represent a promising, cost-saving and flexible alternative for machining applications. Due to the kinematics of a vertical articulated robot the system behavior is quite different compared to a conventional machine tool. This article describes the modeling of the robot structure and the identification of its parameters with focus on the analysis of the system’s stiffness and ...

Operational Modal Analysis (OMA) is a powerful tool, widely used in the fields of structural identification and health monitoring, and certainly eligible for identifying the real in-operation behaviour of vehicle systems. Several attempts can be found in the literature, for which the usage of algorithms based on the classical OMA formulation has been strained for the identification of passenger...

Detection and identification of toxic environmental gases have assumed paramount importance precisely in the defense, industrial civilian security sector. Numerous methods been developed for sensing environment ever since surface acoustic wave (SAW) technology came into existence. Such SAW sensors called electronic nose (E-Nose) sensor use frequency response a delay line/resonator. device is fo...

This paper considers identification of unknown parameters in elastic dynamic models of industrial robots. Identifying such models is a challenging task since an industrial robot is a multivariable, nonlinear, resonant, and unstable system. Unknown parameters (mainly spring-damper pairs) in a physically parameterized nonlinear dynamic model are identified in the frequency domain, using estimates...

The identification process aimed at estimating the model parameters of a COMAU Smart S2 industrial robot for controller design purposes is presented. The principal challenges include the existence of a controller-in-the-loop and the absence of joint sensors for acceleration and velocity measurements. A method valid in this context has been applied, and suitable trajectories were generated to av...

This paper deals with the modelling and identification of a six axes industrial Stäubli RX90 robot. A non-linear finite element method is used to generate the dynamic equations of motion in a form suitable for both simulation and identification. The latter requires that the equations of motion are linear in the inertia parameters. Joint friction is described by a friction model that describes t...

Given the growing tendency of consumers to choose products with natural ingredients, food industries have directed scientific research in this direction. In regard, algae are an attractive option for research, since they can synthesize a group secondary metabolites, called phenolic compounds, associated really promising properties and bioactivities. The objective work was classify major compare...
