This paper presents ongoing work on the formalism of Cyber-Physical Systems (CPS) simulations. These systems are distributed real-time systems, and their simulations might be distributed or not. In this paper, we propose a model to describe the modular components forming a simulation of a CPS. The main goal is to introduce a model of generic simulation distributed architecture, on which we are able...
The article presents results of parametric identification of mechanical part of drive system with permanent magnet synchronous motor by means of heuristic method of Particle Swarm Optimization (PSO). The assumed mechanical part has a complex structure, consisting of two-mass connected by an elastic joint with backlash. The optimization process was designed to find model parameters that assure the...
A Power Hardware in the Loop (FHIL) platform implementation for performing real time simulations of electric systems is proposed. The test bench consists of a FSS'®E real time power flow calculation in combination with a controlled grid emulator. Experimental results are presented to demonstrate the performance of the platform.
The loT (Internet of things) is emerging as a wide variety of devices are attached to the Internet to support ubiquitous and pervasive sensing and computing, home automation, and the shift toward smart cities. As the IoT becomes a critical part of the Global Internet on which we increasingly rely, resilience is increasingly important. Of greatest concern is resilience to large-scale disasters that...
The simulation of transmission and distribution grids comes with a trade-off between the number of modeled components and the modeling depth on the one hand and the simulation speed on the other hand. An example system of a grid converter of a 2 MW full scale converter system is used to show a step-by-step model order reduction. Starting from a detailed switched model the order reduction is shown...
This paper presents a study related to Hybrid Electric Motorcycle (HEM) with a front wheel DC electric hub motor using Lithium Ion battery that renovated from Honda Lead 110cc. The rear wheel is driven by drive train integrated with a continuously variable transmission (CVT) as its origin. Both of them are able to provide propulsion torque separately or simultaneously. Fuel consumption and performance...
The expansion of the Internet of Things (IoT) has resulted in a complex cyber-physical system of systems that is continually evolving. With ever more complex systems being developed and changed there has been an increasing reliance on simulation as a vital part of the design process. There is also a growing need for simulation integration and co-simulation in order to analyse the complex interactions...
This paper presents a new algorithm for finding the parameters that characterize a photovoltaic panel by using the Glowworm Swarm Optimization algorithm. This new algorithm shows great simplicity, flexibility and precision, being able to precisely locate the global optimum point or multiple global optimum points, independently of the initial conditions. The approach here adopted allows the utilization...
Today, most large and complex systems such as aircrafts or power grids integrate physical and human aspects with computing and networking, and therefore constitute so-called socio-cyber-physical systems (SCPS). Their engineering, from prospective and conceptual studies (to determine the scope of the system) through design and construction to operation, maintenance and upgrades, necessitates the cooperation...
This paper illustrates the modelling and simulation (M&S) based engineering approach developed in the framework of ITEA2 project MODRIO to the case of a Backup Power Supply. This system integrates physical and human aspects with computer-based controls, and is therefore a so-called socio-cyber-physical systems (SCPS). This system is relatively simple in terms of physics but is a realistic example...
Coriolis vibrating gyroscopes can be modeled by a planar resonator, using masses, springs and damping. In this paper, the corresponding equations are studied in order to characterize real vibrating cells. It is shown how to present the problem to allow efficient numerical simulations and analytic developments. In particular, the use of the method of Averaging is fundamental, simplifying most of the...
Due to the larger scale of power systems and larger number of converters involved, the simulation of power systems becomes slower, with lower accuracy. FPGA is the new generation computation hardware, which is an integrated circuit designed for a special function. However, FPGA simulation still requires the parallel technology to extend the simulation scale. Network tearing interfaces can be used...
Military modelling and simulation plays a key role in troops training as well as in verification of military scenarios. Most of topics in the modelling of military performance were already successfully implemented into the simulators (like troops moving, fighting, aircraft simulation, etc.) however the simulation of surface (ground) based air defence systems capabilities are not fully developed now...
This paper aims to present a methodology that helps improving systems modelling by using Process Integration and Design Optimization technologies. Then, the methodology has been applied on an automotive case study: the improvement of the hybrid vehicle TOYOTA PRIUS III modelling. This work has been carried out in the context of the international research program PLACIS (PLAteforme Collaborative d'Ingénierie...
Centrifugal pumping systems are the common hydraulic devices mainly driven by electric drives. Their efficiency varies significantly with the change of working point location that depends on the positions of the performance and system curves. This paper is devoted to the study of the pumping system efficiency at throttling and speed control. A model-based calculation method for the single-drive centrifugal...
Electrified guided vehicles are normally equipped with regenerative braking devices, while traction lines are supplied by non-reversible substation, thus allowing braking energy recovery only if nearby other vehicles are absorbing power. To enhance the effectiveness of regenerative braking, some energy storage can be installed along the line. Evaluation of its cost effectiveness requires time domain...

The GUI is built using the MATLAB environment and is able to load and analyze raw test data as its input. After data processing, a cell model is fitted to the experimental data using system identification techniques. The cell model's...

This paper shows control results of simulations on mathematical model and real measurements on the real model of the water tank. The level in the tank is controlled via input volumetric flow rate through the proportional solenoid valve. The adaptive approach with the recursive identification was employed here for controlling of this system. The controller could be tuned by the choice of the pole position...
