Nonlinear System Identification and Soft Sensor Design

Dear Colleagues,

In recent years, nonlinear system identification and soft sensor design have became more significant in various scientific and industrial domains. Nonlinear systems are ubiquitous, found in areas such as Industry 4.0, IoT, biology, economics, and environmental science. The accurate modelling and control of these systems are essential for optimizing processes, enhancing performance, and ensuring safety. Additionally, soft sensors, which are data-driven models capable of estimating unmeasured process variables, play a crucial role in the real-time monitoring and control of complex systems, providing cost-effective alternatives to traditional sensors. Soft sensors are usually designed to exploit nonlinear system methodologies and machine learning/deep learning approaches.

This Special Issue aims to explore the latest advancements, challenges, and applications in the interdisciplinary domain of nonlinear system identification and soft sensor design. By collating researchers from different fields, we aim to foster collaboration and knowledge exchange in this rapidly evolving area.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

• Feature extraction;
• Outlier detection;
• Data selection;
• Big and small datasets;
• System identification;
• Linear and nonlinear models;
• Deep learning techniques;
• Optimization strategies;
• Recurrent neural networks;
• Reservoir computing;

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
