Prototype of Implementation SVPWM Inverter in RTI with V/F Control Based Reluctance Machines Application

Abstract

The paper proposes and investigates a suitable voltage time model implemented in real-time interface. In order to evaluate and compare performance of the emerging brushless doubly-fed reluctance machine (BDFRM) in conjunction with the response to software based architecture a scalar control is integrated into real-time dSPACE platform. The necessary algorithm was integrated and uploaded into dSPACE platform requiring the configuration arrangements of voltage and time vectors. Moreover, machine dynamics and mathematic model were identified, interlinked and synchronised with space vector pulse width modulator (SVPWM). In doing so the time vectors were aligned with RTI microprocessor and/or hardware-in-the-loop (HIL). The RTI library blocks were utilized to enable and substitute the actual machine parameter and match reference data accordingly. Consequently, the controller SVPWM coupled together with the proposed V/f control for the prominent BDFRM have been simulated and experimentally verified under the variable speed operating conditions. The feasibility, correctness and robustness of the proposed controller is validated and corroborated against the qualitative and quantitative data.
