摘要
在状态观测法的基础上提出了一种基于滑模观测器的无位置检测方案,采用线性电感模型,只需电机终端测量到的电压、电流,不需要另外附加硬件,不用考虑探测电流所带来的负面作用,计算量较小,且与传统的状态观测器相比,对参数变化不敏感,具有较强的鲁棒性。
In this paper on the basis of the state observation method was proposed based on the sliding-mode observer position detection scheme,using linear model,inductance motor end to measure the voltage,current,do not need additional hardware,need not consider detection current brings negative effect,small,and the calculation of the state observer compared with traditional,not sensitive to parameter changes,has strong robustness.
