Distributed real-time simulation allows the sharing of simulator equipment and components connected in Hardware-In-the-Loop experiments. In this paper, we analyze the challenges of geographically distributed real-time power system simulation and how dynamic phasors could be applied to improve the accuracy of the simulation results for large time steps. The time step is of particular interest since...
The purpose of a real-time simulation is to provide a closed loop system required for validating the control firmware or application. Detailed plant model with tolerable accuracy and achieving required real-time model execution time are conflicting requirements for a given embedded target hardware. In design of control methods for Pulse Width Modulation (PWM) inverters analytical models are important...
We present an approach to model the deployment costs, including compute and IO costs, of Microservice-based applications deployed to a public cloud. Our model, which we dubbed CostHat, supports both, Microservices deployed on traditional IaaS or PaaS clouds, and services that make use of novel cloud programming paradigms, such as AWS Lambda. CostHat is based on a network model, and allows for what-if...
This paper presents a comparison of several open-loop methods for hysteresis compensation on a lab-made micro-/nanopositioning device. The classical Preisach model with the inverse multiplicative structure, and the Classical/Modified Prandtl-Ishlinskii models with model inversion, are considered. The classical Preisach method though suited for asymmetric hysteresis, does not have an analytic inverse...
Computer simulation is becoming more and more complex to obtain accurate result, which is an obstacle for real-time application such as virtual reality. A method of the Finite Element Analysis (FEA) is proposed to simulate the result of penetration in realtime visual analysis. The FEA software could numerically simulate the process of fragment penetrating target, and analysis the result in visual...
A real-time discrete event simulation platform for Internet end-system targeted attacks, EA-CPNsim, is presented in this paper. This platform provides support for modeling the targeted end-systems behavior and the attack effect, helping the system administrator chooses and verifies the defense schemes, and evaluating the system consequences. EA-CPNsim is constructed based on the CPN tools, a widespread...
