| 摘 要： | 基于滑模变结构观测器(SMO)的基本理论,构造了永磁同步电机(PMSM)矢量控制系统的仿真模型,并对永磁同步电机无位置传感器的转子位置和速度估计算法进行改进,用一个饱和函数代替sign函数,用变截止频率低通滤波器代替固定截止频率低通滤波器,用自适应算法速度观测器代替传统基于电机模型的无位置传感器,实现了无位置传感器对电机转速的准确估算.仿真和实验结果验证了该技术的有效性和合理性.

| Abstract: | A simulation model based on sliding mode observer theory for PMSM vector control is constructed,and sensorless algorithm to estimate the position and speed of the motor rotor based on Sliding mode observer theory is improved.By substituting a saturated function for a sign function,replacing a alterable cut-off frequency low pass filter with a fixed cut-off frequency one,and substituting a parameter self-adaptive observer for a traditional sensorless algorithm based on PSPM model,it has obtained a good perfo... |
