It has always been great challenge for the Aerospace Industries to validate the actual Motor Control Unit (MCU) functionalities while integrating with the real plant (Motor). This integration demands more time and cost because of complex integration requirement and more expensive to install at every testing stage. The control algorithm developer requires the simplified verification target to validate the control algorithm. This in-turn makes the necessity to adopt Low Power Real Time Simulation (LPRTS) System. This paper describes the design and timing challenges of converting simulation model of plant into Real Time Simulation model for precise validation at a high execution rate of up to max-50KHz (20μsec). The higher execution rate requires faster I/O (Input/output) handling, which is managed by the FPGA based configurable I/O device. This paper describes LPRTS with experimental example of Permanent Magnet Synchronous Machine (PMSM) using OPAL-RT.

Diagnosis of the ageing wiring systems in aircrafts, automobiles, industries, transportation, etc is essential. A wide variety of techniques are published in the literature claiming effective diagnosis of wire faults. The focus in this paper is limited to the techniques based on reflectometry principle. These are categorized in to Time Domain Reflectometry [TDR], Frequency Domain Reflectometry [FDR], Spread Spectrum Time Domain Reflectometry [SSTDR], Modified Spread Spectrum Time Domain Reflectometry [M-SSTDR], Noise Domain Reflectometry [NDR], Distributed Reflectometry[DR], Multi Carrier Reflectometry [MCR], Filterbank Multi Carrier Reflectometry [FBMCR] and Time Frequency Domain Reflectometry [TFDR]/Joint Time Frequency Domain Reflectometry [JTFDR] techniques. This paper presents a brief description of these techniques along with their comparison with respect to the key parameters and simulation results of Filter Bank Multi Carrier Reflectometry (FBMCR) technique.
