一种永磁同步电机无传感器控制系统
摘要：
本发明公开了一种永磁同步电机无传感器控制系统，在永磁同步电机矢量控制中，根据Luenberger观测器原理，提出了一种基于Luenberger观测器的PMSM转子速度和位置的估算方法，有效解决了永磁同步电机由于机械传感器的安装带来的一些弊端。利用Matlab/Simulink工具搭建控制系统仿真模型并进行仿真验证，仿真结果表明控制系统具有良好的控制性能。最后，在以STM32F103ZET6为控制核心的硬件系统上进行算法的实现，实验结果表明基于Luenberger观测器的永磁同步电机控制系统具有较高的控制精度且稳定性较好。
摘要（英）：

The invention discloses a permanent-magnet-synchronous-motor sensorless control system. In permanent-magnet-synchronous-motor vector control, according to a Luenberger observer principle, a PMSM rotor speed and position estimation method based on a Luenberger observer is provided so that some disadvantages of a permanent magnet synchronous motor because of installation of a mechanical sensor are effectively overcome. A Matlab/Simulink tool is used to construct a control system simulation model and carry out simulation verification. A simulation result shows that the control system possesses good control performance. Finally, algorithm realization is performed on a hardware system taking STM32F103ZET6 as a control core. An experiment result shows that the permanent-magnet-synchronous-motor control system based on the Luenberger observer possesses high control precision and stability is good.
