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. © 2019 IEEE.

Considering uncertainty in continuous production processes is key to compute short-time optimal schedules which can be trusted in practice. This paper proposes a two-step stochastic approach to the robust scheduling of several evaporation plants. This approach considers the possibility of reacting in the future once the uncertainty materializes. Each evaporator has different features (capacity, equipment, etc.) and the individual performance is affected by external factors and fouling effects. Moreover, a multi-objective analysis has been carried out to provide a decision support for the operator who must take the concrete decisions about load allocation and cleaning tasks along a time horizon. The problem has been solved by discretizing the time horizon and adapting the general-precedence method to deal with an unknown number of tasks. The nonlinear behavior of each plant is approximated by surrogate linear models obtained experimentally, providing thus solutions in acceptable time. © 2017 IEEE.

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. © 2012 IFAC.

Optimal process operation is not always guaranteed due to the presence of significant uncertainty about the plant models that are used to make decisions, for example in Real time optimization, and also due to the differences between control architecture layers which operate on different time-scales and use different kind of models. Modifier adaptation is a methodology that achieves optimality despite the presence of uncertainty by using plant measurements. This paper presents the Nested modifier-adaptation methodology applied to the operation of distillation columns and the results obtained are compared with the previous modifier adaptation methodology using dual control optimization.

This work investigates the topic of solving Bilinear Matrix Inequalities (BMIs) problems in the optimal control design field, using successive resolutions of properly defined Linear Matrix Inequalities (LMIs). This technique can be described as an 'LMI-based coordinate descent method'. Indeed the original (BMI) problem is solved independently for each coordinate at each step using a LMI optimization, while the other coordinate is fixed. No method based on this idea has been formally proved to converge to the global optimum of the BMI problem, or a local optimum in general. This will be discussed using relevant results both from the mathematical programming and control design points of view. This discussion supports the algorithm proposed here which, thanks to a particular change of variables, leads to sequences of improving solutions. Also emphasized is a second improvement important to avoid in practice early convergence to suboptimal solutions instead of local optima. The control framework used is that of optimal output feedback design for linear time invariant (LTI) systems. An example using a random plant is drawn to illustrate the typical effectiveness of the algorithm. © 2011 IFAC.

Iterative Feedback Tuning (IFT) is a tuning method that adjust on-line the parameters in the controller so that a performance criterion is minimised. The IFT method uses only experimental data obtained from the closed loop system without assuming knowledge of the plant or perturbations models. In this paper the application of IFT to the tuning of a PID controller of a pilot plant is reported. The impact on the achieved system performance due to time weighting of the control error is particularly addressed.

This paper presents a comprehensive exploration into the critical aspect of effector design within the context of mobile platforms utilised during emergency scenarios. In times of crisis, ranging from natural disasters to man-made incidents, the efficiency and versatility of mobile platforms equipped with specialised effectors play a pivotal role in ensuring effective response and mitigation. The proposed robotic system consists of a universal platform, a robotic arm, and a custom effector with controls. Our experimental verification of the system shows promising results and the feasibility of the proposed system.

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. © 2024 IEEE.

Smart cities have been a very active research area in the past 20 years, while continuously adapting to new technological advancements and keeping up with the times regarding sustainability and climate change. In this context, there have been numerous proposals to expand the scope of smart cities, focusing on resilience and sustainability, among other aspects, resulting in terms like smart sustainable cities. At the same time, there is an ongoing discussion regarding the degree in which smart cities put people at their centre. In this work, we argue toward expanding the current smart city definition by integrating the circular economy as one of its central pillars and adopting the term smart (and) circular city. We discuss the ways a smart and circular city encompasses both sustainability and smartness in an integral manner, while also being well-positioned to foster novel business activity and models and helping to place citizens at the heart of the smart city. In this sense, we also argue that previous research in smart cities and technologies, such as those related to Industry 4.0, can serve as a cornerstone to implement circular economy activities within cities, at a scale that exceeds current activities that are based on more conventional approaches. We also outline current open challenges in this domain and research questions that still need to be addressed.
