TLDR
In this paper, a sensorless sensorless field-oriented control (SOC) was proposed by exploiting the freewheeling current to accommodate both IGBT and position sensor failures to enhance the drive's fault-tolerant capability.Abstract:
Model-based sensorless field-oriented control (FOC) suffers from overparameterization and can be laborious to use for a five-phase permanent magnet synchronous motor On the other hand, insulated gate bipolar transistor (IGBT) frequently fails in an electric drive Under IGBT failure, a freewheeling current is observed, and, above all, it carries the failed phase back electromotive force information Based on this observation, this article presents the design of a brand new sensorless FOC by exploiting the freewheeling current to accommodate both IGBT and position sensor failures, which is expected to further enhance the drive's fault-tolerant capability The mathematical model of this current is first established to provide a theoretical basis and a comprehensive understanding of the presented sensorless FOC By virtue of this model, a second-order generalized integrator with a frequency-locked loop can be used as a simple and elegant way to extract position/speed estimates Experimental results are provided to validate the proposed sensorless FOC philosophyread more
