摘要:
提出了一种具有抑制转子电阻不确定性对速度辨识影响的转子电阻鲁棒观测器,运用 Lyapunov稳定性理论,构造新的Lyapunov函数,从理论上证明了观测器在全速范围内的稳定性,推导出转速的辨识率。通过与目前流行的转子电阻与转速双辨识方案的仿真比较研究,结果表明:本文提出的转子电阻鲁棒观测器,可在全速范围内很好地抑制转子电阻不确定性对速度辨识的影响,具有很好的鲁棒性能,并且其计算量小,结构简单,且实时性容易满足,在工程实用性上更具优势。
Abstract:
In the technology of sensorless vector control, the rotor resistance uncertainty has important influences on the accurate observation of the rotor flux and identification of the rotor speed. The rotor resistance robust observer which has rotor resistance uncertainty suppression on the speed identification is presented. According to the Lyapunov stability theory, a new Lyapunov function is setted, in theory, could ensure the stability of observer in the full speed range, then the rotor speed adaptive law is deduced. Make a comprehensive simulation comparison with the current popular resistance and the rotor speed dual identification method, the studies show that: the proposed rotor resistance robust observer method in the range of speed has a good suppression of rotor resistance uncertainty on the pace of speed identification and a high robustness, as well as its small amount calculation, simple structure, easily meets the performance of real-time, it has more advantage on the engineering application.
