If it (the machine) is truly dependable, it must be distributed! Do you agree? If not, you are invited to present your thesis or idea.
That is not all, however. Distributed control has another face: the distributed closed loop and/or feedback control.
The first face: Dependability implies distributed real-time control, because we must avoid any possible single points of global failure, including physical damages. Therefore, the functionality has to be redundant (e.g., replicated) and distributed in different physical locations (of the machine). This requires robust real-time communication links and protocols, which normally cannot guarantee the delivery of each and every message. This requires control algorithms which can operate correctly, even in the case of message loss. This implies predictors and mathematical models. Replication is not enough—we need redundancy management and correct state estimation despite inconsistent, contradictory, and/or missing data and measurements, and all of this in real-time.
The second face: We have cooperating independent agents with a common goal. The actions of each one must be coordinated with all others in real-time. These agents are distributed spatially, for example, and controlled by multiple individual controllers which are interconnected. The controllers exchange knowledge between each other and thus provide performance results similar to centralized control systems, while being more reliable (due to redundancy), easier to implement (e.g., if the subsystems are spatially distributed like satellites), and have lower communication requirements than a centralized control. On the other hand, controller design is much more demanding, since each individual controller also has to model some (or all) other agents, and state exchange between the controllers has to be implemented.
You are invited to contribute to or to contradict these theses.

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 papers will be 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. 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 1800 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.
