Model-based Testing Using Real-time Adaptive Simulator
نویسنده
چکیده
Using modeling and simulation users can apply realistic interactions with their synthetic environments representing real world. In this study the synthetic environment is a hardware railroad model representing a miniature replica of a full-size railroad system under study. The hardware model is tested by means of real-time adaptive software simulator consisting of two subsystems: the virtual railroad which mimics behavior of the hardware railroad model, and the controller which is used to synchronize and control the hardware and the virtual railroads. The controller has a built-in feature to forecast possible railroad hazard conditions and to avoid them by sending corrective commands to both railroads. Testing the model can be observed on the simulator screen and on the hardware railroad model. The simulator also features test-event history log allowing playing back the tests.

Soft tissue modeling for the creation of a haptic simulator for training medical skills has been the focus of many attempts up to now. In soft tissue modeling the most important parameter considered is its being real-time, as well as its accuracy and sensitivity. In this paper, ANFIS approach is used to present a nonlinear model for soft tissue. The required data for training the neuro-fuzzy mo...

This paper presents a distance protection test procedure by applying the Real-Time Digital Simulator (RTDS) of a power system. RTDS is a tool to design, develop, and test power-system protection. The RTDS enables real-time computation of electromagnetic phenomena with a calculation time step of even 50μs. The hardware allows the import and export of many signals from the simulator to an ext...
