About
S.G. Abeyratne is a leading researcher in the electrification of high-performance drive systems, with a primary focus on permanent magnet synchronous machines (PMSMs) for transportation and robotics. His work addresses critical reliability challenges in these systems, particularly in the detection and disambiguation of electrical faults that compromise torque density and operational safety. In his highly cited 2022 paper, Abeyratne developed a novel methodology to distinguish between uniform demagnetization faults and position sensor faults in field-oriented control (FOC) PMSM applications—a distinction that is notoriously difficult under wide operating temperatures, field weakening, and low-quality magnet conditions. This contribution is vital for advancing fault-tolerant control in next-generation electric vehicles and industrial robots. With 8 citations already, his research is gaining traction among engineers seeking robust diagnostic solutions. Abeyratne’s work bridges the gap between theoretical fault analysis and practical, high-reliability motor drive design, positioning him as a key innovator in the push toward safer, more efficient electrified transport and automation.
