The SmarFuel project aims to develop a new generation of AFMS (Aircraft Fuel Management System). It proposes a Distributed Avionics control architecture (DACA) based on networked Smart Fuel Components (SFCs). This decentralized solution (opposite to conventionally-centralized approaches) reduces avionics wiring whilst the AFMS is fault tolerant. The DACA is realized by distributing the control system through microcontrollers embedded in SFCs and across a fieldbus. Thus, SFCs are able to implement advanced functions such as auto-calibration. The AFMS operation modes considered are three: pressure refueling, engine supply, and fuel transfer. The operation sequence of AFMS events is not fixed which makes the SFC decision-making process critical. The above DACA for AFMS was already realized and evaluated successfully in laboratory prototypes. This paper presents experimental results from verification and validation tests of the DACA realization carried out in a real-scaled helicopter rig. These ground experiments are based on the above fuel system operations. This paper also presents a verification tool for the SFC state machines. Conclusions and future research directions are also discussed.

Symbolic Regression for Marine Vehicles Identification ∗

The mathematical models used in simulation must be reliable and trustworthy enough to describe the real systems with an appropriate accuracy. This simulation process is specially important in marine environment due to the changing environmental conditions, to the cost of the infrastructure needed to carry out tests, and to the need of calibration, deployment and recovery of the marine systems. If a reliable mathematical model of the vehicle is available, a part of the experimental tests can be avoided. In this paper we present a system identification technique based on genetic programming, the symbolic regression, to be applied on marine systems. In this sense, we show that it is possible to obtain a mathematical model of a ship for control purposes without the need of describing or knowing the model structure in advance, i.e., the identification itself provides the model structure that better describes the system. Thus, we can define a reliable black-box model that is computed in a simple way and where no many experimental data are needed. The model obtained is tested with additional data and manoeuvres to show its good performance and prediction ability.

7th International Conference on Intelligent Systems and Knowledge Engineering, ISKE 2012

作者： Mikati, Monir Santos, Matilde ÅF Technology Lindholmspiren 9 41756 Gothenburg Sweden Department of Computer Architecture and Automatic Control Universidad Complutense de Madrid 28040 Madrid Spain

In this paper we have developed a methodology and a numerical model for sizing photovoltaic (PV) arrays for grid-connected power consumers. The decision variables proposed are the PV contribution to the power demand and a transfer factor. The latter is a new index that we have defined, and it constitutes key knowledge for decision making when aiming to reduce power transfers between a local power system and the electric grid. The developed model generates days of solar irradiance and calculates PV power output for commercial PV modules. Sizing diagrams are presented that illustrate how the PV capacity, for a specific location and a local power demand, affects the PV contribution to the demand and the power trades with grid. For the particular simulation conditions studied, the sizing diagrams show PV contribution saturation levels and global transfer factor minimums. © Springer-Verlag Berlin Heidelberg 2014.

The concept, functional aspects, and experiments based on lab prototypes of an innovative approach for aircraft fuel management have been developed in recent years. The main approach innovation is the replacement of the conventional central fuel computer with distributed and interconnected Smart Fuel Components (SFCs). This solution lowers the wiring weight, reduce the chance of a faulty connection, and simplify maintenance. This paper presents the experimental results obtained from ground and flight tests carried out on the implementation the above approach in a twin-engine helicopter. The SFC software is deployed in the helicopter in ground to be tested. Once the results obtained from the ground test are accepted, the same SFC software is tested in flight. The ground-tested and flight-tested functions for the fuel control system are: fuel supply, display of fuel levels, fuel transfer, refueling/defueling, measurement of height, density and flow of fuel, and monitoring/surveillance. The objectives of the ground and flight tests are to prove secure engine fuel supply for engine "two" during flight, reliable fuel gauging during flight, and the above selected functions as basis for system operability. This paper also describes the testing cases and criteria, and the main project achievements for ground and flight tests in a twin-engine helicopter.

• Automated design and synthesis processes to develop a HDFCShave been presented. • Tests carried out on simulations demonstrate that the results (main focus on the software code automatically generated, i.e. state-machine) obtained from the above processes are according to what has been specified. • The state-machine generated works as expected in the simulator. However, there are some cases (near the limits of the tank capacities) in which the state-machine (software implementation, i.e. code generated automatically) makes some states of valves oscillate.

The aim of this article is to analyse the results obtained when using a genetic algorithm (GA) to optimise the interplanetary trajectory of a spacecraft. The desired trajectory should visit Saturn, after performing a gravitational assistance or fly-by in planet Mars. The GA tunes a set of variables, in order to achieve the mission purpose while satisfying the constraints and minimizing the delta-V of the mission. Due to the complexity of the implemented models and the lack of analytical solutions, an alternative non-traditional algorithm provided by soft-computing techniques such as GA is necessary to achieve an optimum solution. The positions of planets as provided by Jet Propulsion Laboratory have been considered. A variable mutation rate has been implemented that broadens the search area whenever the population becomes uniform. The results are very useful from the point of view of mission analysis and therefore can be used as an initial guess for further optimizations. They can also be the first step for a more refined analysis and time-consuming simulations based on more complex models of orbital perturbations. © 2010 IEEE.

IEEE International Conference on Fuzzy Systems (FUZZ-IEEE)

作者： Joshué Pérez Agustín Gajate Vicente Milanés Enrique Onieva Matilde Santos CSIC Instituto de Automática Industrial Arganda del Rey Madrid Spain Department of Computer Architecture and Automatic Control Universidad Complutense de Madrid Madrid Spain

The control of nonlinear systems has been putting especial attention in the use of Artificial Intelligent techniques, where fuzzy logic presents one of the best alternatives due to the exploit of human knowledge. However, several fuzzy logic real-world applications use manual tuning (human expertise) to adjust control systems. On the other hand, in the Intelligent Transport Systems (ITS) field, the longitudinal control (throttle and brake management) is an important topic because external perturbations can generate uncomfortable accelerations as well as unnecessary fuel consumption. In this work, we utilize a neuro-fuzzy system to use human driving knowledge to tune and adjust the input-output parameters of a fuzzy if-then system. The neuro-fuzzy system considered in this work is ANFIS (Adaptive-Network-based Fuzzy Inference System). Results show several improvements in the control system adjusted by neuro-fuzzy techniques in comparison to the previous manual tuned controller, mainly in comfort and efficient use of actuators.
