The paper presents an approach to evaluate modulation techniques in a Grid-Tied two-level Inverter using Test-Driven Design (TDD). It presents a set of tests that collect and calculate performance, harmonic, and power metrics of the inverter, based on IEEE Standards. The results are obtained by a Hardware-In-the-Loop (HIL) simulation and the TDD is applied with the pytest framework and Python language. The results of TDD procedure offer a structure to analyze different characteristics of the modulation approaches considering the Half-Bridge converter and the Space Vector, Sinusoidal and Carrier-Based algorithms.

Hil Simulation

Hardware-in-the-Loop (HIL) Simulation enables testing of an actual physical component of a system under a variety of conditions without the expense of full scale testing. In hydraulic systems, flows or pressures that interface with the component in question are controlled by a computer running a simulation designed to emulate a complete system under real operating conditions. Typically, servo valves are used as actuators to control the flows or pressures. This paper investigates the use of electric servo-motors coupled to hydraulic gear motors as alternative actuators, and discusses some of the advantages and disadvantages that motors have in comparison to valves. A demonstration HIL simulation involving a mobile proportional flow control valve attached to an emulated backhoe is described, and results are compared to data from a real backhoe.

Hil Simulation

In the hardware-in-the-loop (HIL) simulation of the fuel control unit (FCU) for aero-engines, the back pressure has a great impact on the metered fuel, thus influencing the confidence of the simulation. During the practical working process of an aero-engine, the back pressure of the FCU is influenced by the combined effect of the pressure of the combustion chamber, the resistance of the spray nozzles, and the resistance of the distribution valve. There is a need to study the the mimicking technique of FCU back pressure. This paper models the fuel system of an aero-engine so as to reveal the impact of FCU back pressure on the metered fuel and come up with a scheme to calculate the equivalent FCU back pressure. After analyzing the requirements for mimicking the pressure, an automatic regulating facility is designed to adjust the FCU back pressure in real time. Finally, experiments are carried out to verify its performance. Results show that the mimicking technique of back pressure is well suited for application in HIL simulation. It is able to increase the confidence of the simulation and provide guidance to the implementation of mimicking the FCU back pressure.

Aufgrund der Notwendigkeit, die Qualität der Herstellung und Installation eines gravimetrischen Dosiersystems für Schüttgüter zu verbessern, wurde ein automatisches Testsystem entwickelt, das auf Basis einer Hardware-in-the-Loop (HiL)-Simulation in der Lage ist, die notwendige Werksabnahme des gesamten Systems durchzuführen. Das im Beitrag beschriebene Testsystem besteht im Wesentlichen aus einer Echtzeit-HiL-Simulation und den notwendigen Schnittstellen auf Basis von Standardkomponenten, einer Benutzerschnittstelle zur Definition der Testroutinen und einer Verifikationsmaschine (verification engine) für die selbsttätige Datensammlung und nachgelagerte Validierung und Protokollierung. Auch wenn die Applikation derzeit noch im Rahmen von Tests weiter evaluiert wird, konnte bereits gezeigt werden, dass das vorliegende Testsystem und die zugrundeliegende Architektur in der Lage sind, die notwendigen Testprozeduren vollständig durchzuführen; eine gewählte modulare Struktur garantiert die notwendige Erweiterbarkeit für andere Applikationen.
