This paper describes an approach to optimal management of hydrogen networks in refineries, focusing on the problems of reconfiguration that appears when, due to plant failures, the production of the hydrogen generating units suddenly decreases. The problem is formulated in terms of optimization as a MINLP one. Also, guidelines to the implementation of the optimum are presented with the aim of providing a practical solution to the inherent uncertainly and changing dynamics associated to the process.

Open space exploration is difficult to carry out directly from the Earth's surface. Lunar bases, the construction of which is announced by various countries, are considered as transit points for spaceships and spacecrafts heading further to the planets of the Solar system and open space. However, for any movement in the space the energy is required, and the source of the energy is fuel. It is not always advisable and almost impossible to deliver the needed amount of a fuel to the Moon from the Earth. In this paper we consider one of the possible solutions to build a flexible mobile production system for producing of a fuel from the ore, which could be found on the lunar surface. The technology for such reprocessing has already been defined, then, a system is required that will be able to produce fuel and supply spaceships and spacecrafts in an autonomous mode. The specifics and composition of such system are described, the layout of the system was simulated. The calculations of the core resource of the system are provided.

This work studies input-output stability of time-delay reset control systems, with first order reset elements (FORE). The results are derived by using integral quadratic constraint (IQC) framework. A new delay-dependent stability criterion is formulated in the form of a linear matrix inequalities (LMI) condition, using Kalman-Yakubovich-Popov (KYP) lemma. A numerical example is given, which illustrates the effectiveness of the new criterion.

The increasing global concern regarding humane pest control methods and the need for effective small mammal management in various environments have prompted the development of innovative technologies. This paper presents our ongoing design of a novel smart non-lethal trap prototype for small animals equipped with an ESP32-CAM and PIR sensor. To differentiate between domestic pets and rodents, ResNet50 is utilised and capable of classifying five animals: cats, dogs, martens, rat or mice, and hedgehogs. Traditional rodent control methods often rely on lethal means, which pose ethical and ecological challenges. Most pest control businesses also use the labour-intensive strategy of physically setting up and maintaining rodenticide bait stations on a commercial basis. To address these issues, our prototype leverages the capabilities of the ESP32-CAM to create an intelligent non-lethal trapping solution with the ability to remotely free unwanted captured animals via the cloud.

In this letter, we propose a control scheme for regulating the voltage in Direct Current (DC) power networks. In contrast with other works in the literature where the loads are assumed to be constant, we consider uncertain time-varying loads described as the outputs of nonlinear dynamical exosystems with uncertain parameters. Based on the output regulation methodology, the proposed control scheme ensures the robust stability of the overall network and achieves voltage regulation in presence of impedance (Z), current (I), and power (P) loads. The simulation results illustrate excellent performance of the proposed control scheme.

A Sum-Of-Squares Constrained Regression Approach for Process Modeling

Combining empirical relationships with a backbone of first-principle laws allow the modeler to transfer the available process knowledge into a model. In order to get such so-called grey-box models, data-reconciliation methods and constrained regression algorithms are key to obtain reliable process models that will be used later for optimization. However, the existent approaches require solving a semi-infinite constrained regression nonlinear problem, which is usually done numerically by an iterative procedure alternating between a relaxed problem and an a posteriori check for constraint violation. This paper proposes an alternative one-stage efficient approach for polynomial regression models based in sum-of-squares (convex) programming. Moreover, it is shown how several desirable features on the regression model can be naturally enforced in this optimization framework. The effectiveness of the proposed ap-proach is illustrated through an academic example provided in the related literature.

Application of SOS-constrained regression to model unknown reaction kinetics

The key idea of the fourth industrial revolution is to use the huge amount of data from the increased process digitalisation in order to make better decisions at all levels: from the design and control, to operation and management. However, advanced decision support systems usually rely on good plant models. Despite the increased popularity of machine learning, in the process industry many of these approaches may fail in building reliable prediction models: that is, models whose output can be trusted even out of the region where actual data was collected. This paper illustrates how to get a reliable grey-box model of a chemical plant for optimisation purposes via sum-of-squares (SOS) constrained regression, a method that guarantees full enforcement of physical features on the identified model, no matter the quality and quantity of the collected data. The approach is used here to identify a reliable model for the reaction kinetics in a hybrid CSTR, a pilot plant where the chemical reactions are emulated over a harmless fluid.
