   A FPGA Based Pwm Synchronised Modulator And Measurement Unit
By Waldemar Sulkowski, Dag A. H. Samuelsen [View]
[Download]

Abstract: This article presents a measurement sampler and PWM modulator integrated within the same unit. This solution makes possible the use of timing data from the PWM to facilitate the control of the analog to digital (AD) converters and to avoid the current transients that occur during commutation of the power converter. It makes possible to have exact measurement of the derivatives of the currents. This relieves the DSPprocessor of processing load. The DSP can then be set to do other time consuming tasks. This sampler and modulator are set up in a FPGA device with six AD converters in parallel. Practical tests are included in the paper.

   Logging Sensors Measurements To A Remote Database Using Labview And Fieldpoint
By Mihaela Lascu [View]
[Download]

Abstract: Using the networking features in LabVIEW it is possible to perform following tasks: share live data with other VI's running on a network, publish front panel images and virtual instruments documentationon the web, build virtual instruments that communicate with other applications and virtual instruments through low-level protocols. The main task of the paper is to create a virtual instrument for acquisition, control and monitoring temperature in eight points inside of an airplane, to create storage of the data in data files and to send the data to Remote Computers, that means to log temperature data to Remote Databases.

   Real Time Torque And Power Analyses Of Electromechanical Systems
By Jaroslav Novak, Stanislav Gregora, Vladimir Schejbal [View]
[Download]

Abstract: The structure of computer program for indirect determination of induction motor torque using mathematical model computation is presented. The possibilities of extension of the program for analyses of AC motor power are given along with the program algorithm for power analyses. Moreover, the accomplishment possibilities of direct tensometer torque sensors are studied.
