PMLSM无位置传感器检测技术的研究

Research of PMLSM's Position-Sensorless Detecting Technology

详细讨论了永磁直线同步电机(PMLSM)基于模型参考自适应理论(MARS)无位置传感器的检测技术,在没有位置传感器的情况下检测PMLSM的位置、速度,消除了由位置传感器带来的误差,应用Popov超稳定性理论证明了该检测系统的稳定性。并用Matlab/Simulink软件对PMLSM的无位置矢量控制系统进行了仿真研究,仿真结果表明该检测系统具有令人满意的估计精度和动态性能。

PMLSM＇s detecting technology based on MARS was discussed. PMLSM＇s position and speed without position sensor was detected,error created by position sensor and testified stabilization of the detecting system by applying Popov super stabilization theory was eliminated. The simulation researches were tested on the position - sensorless vector control sys- tem of PMLSM by using the software Matlab/Simulink. The simulation results showed that this MRAS speed estimation model had satisfied estimation precision and dynamic performance.
