| 摘 要： | 在交流调速领域，电机磁链的精确控制是实现高性能变频器的关键。通过控制原理方法分析不同的磁链模型，在Matlab/Simulink环境下，建立并对基于滤波原理、积分负反馈频率自适应原理和锁相环MT轴系原理电压模型进行比较，完成电压模型的优化选择。同时，建立励磁同步电机闭环控制系统，实现同步电机带载启停过程中电压模型与电流模型的平滑切换。

| Abstract: | Flux observer is the key for high performance frequency converter in the field of AC speed regulation. The various flux models are analyzed by control theory. The voltage model is built in Matlab/Simulink based on fil-ter theory and integral negative feedback frequency adaptive theory and compared with phase-locked loop MT axis voltage model. At last, superior voltage model is selected. Meanwhile, the excitation synchronous motor closed-loop control system is built to realize smooth switching between voltage model and current model while motor start-ing and stopping on load. |
