摘要
Abstract
To address the issues of high-frequency chattering and harmonic interference in traditional sliding mode observers for high-speed permanent magnet synchronous motors(HPMSM)under low carrier ratio conditions,an adaptive discrete full-order sliding mode observer suitable for such conditions was designed.This observer employed a quasi-proportional resonant regulator instead of the traditional sign function,effectively filtering out high-order harmonics in the observer's state variables,reducing system chattering,and thus obtaining accurate observed back electromotive force.To accurately extract rotor position information,a phase-locked loop strategy based on complex coefficient filters was further proposed.Aiming at the coupling issue between the phase-locked loop and complex coefficient filters,an adaptive speed estimator with dynamic compensation was designed,which effectively solved the problem of increased rotor position estimation error caused by such coupling under low carrier ratios.Finally,experimental verification shows that the proposed strategy can maintain good dynamic response and stability under low carrier ratio conditions,meeting the requirements of high-precision control.关键词
