Hardware in the Loop Testing of Eobd Strategies
نویسنده
چکیده
European regulations regarding exhaust gas emissions have constantly become more restricted in the last decades. Components of the exhaust gas after-treatment system and ECU strategies have become correspondingly more complicated in order to fulfil the prescribed limits. This paper describes how a real time HIL engine simulator can be used to test EOBD ECU strategies, in order to reduce the amount of costly experimental tests. Strategies for the exhaust gas after-treatment system have been tested on HIL. The results of the tests show the feasibility of HIL testing of EOBD strategies. Copyright © 2002 IFAC

Distance protection closed-loop testing using RTDS
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...

Aerodynamic load simulators generate the required time varying load to test the actuator’s performance in the laboratory. Electric Load Simulator (ELS) as one of variety of the dynamic load simulators should follows the rotation of the Under Test Actuator (UTA) and applies the desired torque to UTA’s rotor at the same time. In such a situation, a very large torque is imposed to the ELS from the...

متن کاملHardware-in-the-loop Testing of Continuous Control Algorithms for a Precision Formation Flying Demonstration Mission “18 International Symposium on Space Flight Dynamics”
A sample mission sequence is defined for a low earth orbit demonstration of Precision Formation Flying (PFF). Various guidance navigation and control strategies are discussed for use in the PFF experiment phases. A sample PFF experiment is implemented and tested in a realistic Hardware-in-the-Loop (HWIL) simulation using the Formation Flying Test Bed (FFTB) at NASA’s Goddard Space Flight Center.
