    摘要:

    以脈振高頻電壓信號注入法無位置傳感器控制技術(shù)為基礎(chǔ)，設(shè)計了永磁同步電機位置傳感器容錯控制系統(tǒng)。對高頻電流信號和解調(diào)信號間存在相位延時的問題進行了分析，指出該相位延時是逆變器延時、定子電阻延時和AD采樣延時的共同作用。分析了互感和諧波電感對位置估計誤差的影響，提出相應(yīng)的補償方法。仿真和實驗結(jié)果表明，所設(shè)計的位置傳感器容錯控制系統(tǒng)跟蹤精度高，具有一定的抗擾動能力，可以很好地進行零速和低速時的速度和位置估計。

    Abstract:

    Based on fluctuating high frequency voltage signal injection sensorless control method, position sensor fault-tolerant control system for permanent magnet synchronous motor (PMSM) was designed. The phase delay, which existed between high frequency current signal and demodulated signal, was analyzed. The phase delay was caused by the inverter, the stator resistance and AD sampling time. The effect of the mutual inductance and the harmonic inductance on position estimation error were analyzed. And a compensation method was proposed. Simulation and experiment results showed that the position sensor fault-tolerant control system had the advantage of high tracking accuracy and certain disturbance-rejecting ability. It had also a good speed and position estimation performance at zero and low speed. 
