This paper presents a virtual sensing approach for monitoring the elevator installations. The aim of the proposed virtual sensing approach is to monitor the condition of elevators without installing additional sensors. The adopted virtual sensing approach comprises a coupled-electromechanical elevator model presented in state space domain and a gen...

The aim of the present study was to determine if the electrodermal activity (EDA) associated with the drinking experience of different beer samples could be related to consumers' self‐reported response (liking, emotional valence, and arousal) in two contexts: a sensory lab and a restaurant. A total of 129 consumers participated in the study; after...

In a context where industrial production boosts both the society and the economy of a country, improvements in industrial processes are key factors for efficient and reliable development of goods and products. New industrial processes and machines must be evaluated before deployment at large production scales. This paper proposes a new optimized de...

Condition monitoring is a crucial task for electromechanical system reliability and quality enhancement, which allows early electrical and mechanical faults detection, leading to a predictive maintenance. The aim of this paper is to analyze the feasibility of a virtual sensing approach to perform a health diagnosis in the context of elevators. The...

Condition monitoring is a crucial task for electromechanical system reliability and quality enhancement, which leads to early electrical and mechanical faults detection. In this paper, the design of a scaled test bench including its main subsystem components at initial stage is presented for the assessment of new methods dedicated to electrical and...

The assessment of the contact and friction forces acting on guiding rails is of high importance in the design and maintenance of mechanical systems. The direct measurement of these forces is however difficult as the use of a dedicated sensor is impractical and in some cases unfeasible. The use of model-based virtual sensing approaches is an attract...

Model-based virtual sensing techniques are a valuable approach to estimate system variables which are difficult to measure. Instead of measuring these variables directly, physics-based models and estimation algorithms are used to compute them. As the system grows in complexity the use of dedicated modeling tools is required to reduce modeling effor...

In this paper, a dynamic model for an elevator installation is presented in the state space domain. The model comprises both the mechanical and the electrical subsystems, including the electrical machine and a closed-loop field oriented control. The proposed model is employed for monitoring the condition of the elevator installation. The adopted mo...

his paper presents a model-based monitoring approach for the estimation of the elevator rail friction forces. This model-based monitoring approach is based on a Linear Parameter Varying (LPV) model of a 1:1 elevator installation, comprising both the mechanical and the electrical subsystems. The Extended Kalman algorithm (EKF) is then employed as an...

Condition monitoring is a crucial task for elevator installation reliability and quality enhancement and leads to an early electrical and mechanical faults detection which can reduce the maintenance cost and avoids failures. The performance of a condition monitoring system should be evaluated before its installation on an actual full-size system. T...

Lifts are the most common solutions in vertical transportation industry. This growing business has changed the tendency followed during the last years, appearing nowadays maintenance as a key point of action, as it has become a 50% of the economical lift market. However, in authors’ opinion, a maintenance strategy which involves the condition evalu...
