Edson B. M. Costa, Ginalber L. O. Serra
The presented fuzzy gain scheduling control design approach has been tested in real-time experiments applied to a time varying delay nonlinear thermal plant. The data acquisition platform is composed of a virtual instrumentation environment, data acquisition hardware, sensor, and actuator, as shown in Figure 4.3. The thermal plant consists in an adapted monophasic toaster AC 220 volts, with functional temperature from 25 °C to 200 °C. The virtual instrumentation environment (Human Machine Interface) is based in LabVIEW software (LABoratory Virtual Instrument Engineering Workbench) which allows the designer to view, store, and process the acquired data. The data acquisition hardware performs the interface between sensors/actuators and the virtual instrumentation environment, and is composed of the NI cRIO-9073 integrated system, the NI 9219 analog input module, and the NI 9263 analog output module. The temperature sensor is the LM35, and the actuator is based on TCA 785.

Virtual instrumentation (VI) is a multifaceted field to combine software and hardware technologies so as to create instruments both sophisticated and flexible for monitoring as well as control applications. There are quite a few descriptions of a Virtual Instrument. A Virtual Instrument as described by Santori is “an instrument whose capabilities and general functions are decided by the software” [1].Goldberg says “A Virtual Instrument is made up of various general-purpose computers, some software, a few dedicated subunits and a little technology” [2,3].These descriptions capture the fundamental ideas of VI and virtual concepts overall which are affordable: “any computer can replicate another, if it is loaded with software to simulate another computer” [4].
VWF and Online Laboratory
Published in Chinmay K. Maiti, Introducing Technology Computer-Aided Design (TCAD), 2017
Electronic/electrical measurement-based experiments may be conducted using different technologies. However, used technique could be unique to that experiment and also in the tools used to publish them over the Internet. Java is commonly used to provide a good base for Internet functionality and standardization across different computer hardware and operating systems (OSs). Choosing the best technology for remote-controlled laboratories development is dependent on several criteria such as, the current status of the technology, the development time, and the system independency of the user in terms of the OS and Internet browser as well as other necessary installations. Also the design and operation of the experiments are topic/domain dependent. Different tools are now available like, National Instruments (NI) LabVIEW (Laboratory Virtual Instrument Engineering Workbench) to publish the developed environment in the web. To minimize special purpose hardware and software investment, our system has been developed around LabVIEW software and NI hardware. LabVIEW program is one of the high level programming languages that is preferred in this study to perform VL applications. LabVIEW software provides an active and controllable interface for test, measurement, instrument control, data processing, and data analysis applications. Virtual instrumentation is a new technology paradigm which leverages all the continuing advancements in processor/PC technologies, bus standards, and Internet-based communication, software standards, protocols, and all application and network connectivity features. VIs are developed using LabVIEW to display process variables, set control parameters, and indicate the outcome. HP-VEE and other popular programming environments may also be used for VI development. Laboratory developers can either deploy the instrument through an online laboratory management system or develop their own management system using the package.

The main purpose of carrying out the present experimental work is to simulate in-flight conditions in aircraft engine combustor fueled with biofuel and assess the resulting emissions. In the present investigation, a can combustor supplied by PWC has been employed. Other equipment employed for the experimental program are emission analyzer, mass flow meter for air, pressure sensors, temperature sensors, fuel flow meter, and high pressure pump for cooling water spray. Added instruments are virtual instrumentation setup using Lab-View software with data acquisition system and inlet–exit control valves. The experimental scheme is depicted in Figure 1. High pressure and temperature conditions are developed for inlet air in order to emulate actual flight conditions. This is done by means of an air compressor and electric furnace as given in Figure 1. The experimental tests were carried out according to the operating conditions as illustrated in Table 1. The details of different fuels employed during the experimentation are listed in Table 2.
Power quality analysis of 6 kW building-integrated photovoltaic system and economic evaluation using RETScreen™
Published in International Journal of Ambient Energy, 2018

The monitoring system was developed using the Virtual Instrumentation concept (Johnson and Jennings 2006). Thus, compact DAQ devices of National Instruments Company were used as hardware and the LabVIEW (Laboratory Virtual Instrument Engineering Workbench) package (Bishop 2007) was used as software. The system includes sensors and transducers for measuring the parameters required to determine the performance and the power quality of the PV system.
