“…24,25 To this aim, in previous works, the authors have developed a MATLAB-Simulink library, called Transient Thermal Hydraulic Library (TTH Lib), for the integrated simulation of thermal-hydraulic plants, such as the auxiliary lubrication circuits. 26 In this article, both a model-based approach for the simulation of a whole auxiliary lubrication plants and a PID control optimization approach based on the flexible simplex technique for the plant regulation are proposed. More in detail, authors aimed at developing an accurate lumped parameter model, especially in transient operation, characterized by an accuracy similar with the ones of complete 3D models, however, with a higher efficiency degree, optimizing the trade-off between results accuracy and execution efficiency.…”

In the Oil & Gas industry, the testing of auxiliary lubrication plants represents a mandatory preliminary activity before the whole turbo-machinery train (including the auxiliary lubrication plant) can be put in operation. To this end, the employment of both efficient and accurate plant models becomes very important to synthesize satisfactory control strategies for both testing and normal operation purposes. This way, many benefits (e.g. in terms of safety, times and costs of execution) can be achieved. Therefore, this article focuses on the development of innovative and efficient real-time models and control architectures to describe and regulate the auxiliary lubrication systems. All the new strategies have been validated through accurate real experimental campaign and real-time hardware. According to the Bond-Graph modeling strategy, an efficient lumped parameter model of the lube oil console has been built to properly optimize the description of such system and the efficiency of the control strategies. The code has been compiled and uploaded on a commercial real-time platform that has been used to regulate the pressure control valve of the physical plant (to this aim, a new regulator has been developed). In particular, the control was designed according to a novel model-based methodology, including both identification and control optimization techniques (based on flexible simplex techniques). The comparison between the data obtained from the simulated system and the ones acquired from the physical plant shows the good agreement, reliability and efficiency of the proposed model and the control strategy. Both the modeling approach and the control strategy have been developed in collaboration with Baker and Hughes General Electric, while the experimental data were acquired in a plant located in Massa (Italy).

“…Finally, it is also interesting to notice that the secondary pad installed on a car should be able to work with different primary pads affected by tolerances due to different typologies, installation procedures or even suppliers (Bululukova et al, 2014) In this work an original interpretation of the problem based on the bond-graph approach is proposed (Karnopp et al, 1990;Borutzky, 2011). Bond-graph approach is often adopted for the dynamical modelling of multi-physics systems such as steam (Pugi et al, 2015), hydraulic (Pugi et al, 2014) or pneumatic (Pugi et al, 2004) networks. Aim of the proposed approach is to provide the designer of more intuitive tools and methodologies to understand and optimise parameters affecting the sizing of the system.…”

Wireless recharge of electric vehicles is an important field of research. By means of tools used for modal analysis of vibrating systems, this paper proposes an innovative approach which is applied to the study of an inductive power (IPT) transfer system with series-series compensation. One of the main advantages of the proposed approach is the possibility of an intuitive physical interpretation. Another contribution of the work is definition of a new dimensionless parameter to optimise applied load with respect to efficiency issues. Numerical and experimental results confirm the validity and feasibility of the proposed approach.

“…Inertial effects which are usually with lumped mono-dimensional elements (I) are neglected considering the low dynamical behaviour of the plant. The adopted approach is quite common in literature [20] and also adopted by authors for the simulation of plants and fluid networks with uncompressible [21] compressible fluids [22] or multiphase one, such as steam [23]. Dynamical behaviour of the controlled 4/3 valves: valves are modelled considering the equivalent response of a second order system (eq.…”

h i g h l i g h t sAn innovative on board hydraulic system fed by a KERS is presented. A complete model of the proposed system is presented. The model is validated on experimental data. a r t i c l e i n f o a b s t r a c tMany conventional truck and working machines are equipped with additional hydraulic tooling or manipulation systems which are usually fed through a mechanical connection with the internal combustion engine, involving a poor efficiency. In particular, this is a common situation for industrial vehicles whose mission profiles involves a relevant consumption of energy by the on board hydraulic systems, respect to the one really needed for only traction purpose. In this work it is proposed an innovative solution based on the adoption of a system aimed to recover braking energy in order to feed an efficient on board hydraulic actuation system. The proposed system is then adopted to a real application, an Isuzu truck equipped with a hydraulic tooling for garbage collection. A prototype of the system has been designed, assembled and tested showing a relevant improvement of system efficiency and the feasibility of the proposed approach. In the paper the proposed solution is presented, showing the simulation models and preliminary validation results including experimental devices assembled to perform the tests.
