Abstract This paper presents a method for detecting resolver offset in Permanent Magnet Synchronous Motors (PMSM) using LabVIEW software. PMSM systems rely on accurate position sensing for efficient control, and the resolver is a key sensor. However, resolver offset can degrade control accuracy. The research focuses on developing a real-time signal processing and offset detection algorithm using LabVIEW. The experimental results demonstrate that the proposed method enhances detection precision and improves system stability. Future work will focus on optimizing the algorithm and expanding its applicability to complex control environments.
