Dear Colleagues,

Many industries have heat diffusion systems incorporated in their processes. Due to the delay in reaching the desired temperature and the dificulty of maintaining this value, several control algorithms have been developed in the last decades to produce better systems responses. In the previous century, the most common algorithms used in the control of systems were PID controllers, with their tuning parameters based in the Ziegler–Nichols or Cohen–Coon methods. More recently, several other methodologies have been implemented using genetic algorithms, particle swarm optimization, fuzzy control systems, and other algorithms, which were found to be helpful tools for determining the parameters of the controllers, consequently improving this kind of system. These algorithms introduce concepts based on nature, evolution, or human knowledge to better tune the PID parameters. This Special Issue seeks to gather contributions to the control of heat diffusion systems using these suggestions or other methodologies, such as the incorporation of fractional order controllers.

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 100 words) can be sent to the Editorial Office for announcement on this website.

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. Energies 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 2600 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.
