Abstract

In permanent magnet synchronous motor (PMSM) system, the offset current demonstrates time-varying behavior under the influence of environmental temperature variations and changing operating conditions. If left unmitigated, this phenomenon can induce significant additional periodic fluctuations in motor currents, thereby compromising the stability and control precision of the entire system. To effectively address this challenge, this paper introduces an online offset current compensation strategy. The proposed approach employs a quasi-resonant controller to accurately extract characteristic harmonic components, formulates the offset current using expressions composed of multiple trigonometric functions, and realizes real-time online compensation through integral approximation. The effectiveness and superior performance of the proposed compensation scheme are comprehensively validated via a developed simulation model.
