Abstract

Electronic devices exposed to non-ionizing radiation are susceptible to Single-Event Upsets (SEUs) in digital systems. These SEUs can lead to failures in the digital system of Brushless DC (BLDC) motor drivers, resulting in data reading errors, speed control malfunctions, phase commutation inaccuracies, and erroneous rotor position detection, which can have significant consequences in critical situations. Thus, this paper proposes to enhance the reliability of a Proportional-Integral (PI) speed control system for BLDC motors by employing the Triple Modular Redundancy (TMR) technique implemented within an FPG Artix-7. The results of the control efficiency are evaluated through its performance characteristics given through simulation and implementation. The fault tolerance validation of this proposal was carried out through fault injection campaigns. The results demonstrate that the TMR-based system can tolerate around 115% more faults than a non-TMR system, highlighting the robustness and reliability of the proposed solution.
