摘要：基于分数阶文积分和自抗扰控制，设计了永磁同步电机转速伺服控制系统。该方法采用分数阶微积分比整数阶更广的参数稳定域的特点，与自抗扰控制对未知干扰的高观测性能结合，同时，采用双线性变换和连分式展开法推导出分数阶积分的离散模型，建立分数阶比例积分非线性反馈环节，以增强系统对扰动的鲁棒性能。仿真试验中，将其与采用非线性函数的自抗扰控制器进行了比较，结果验证了所提出的方法的有效性。

Abstract: With respect to problems in the management of permanent magnet synchronous motor vector, the PID controller caused less dynamic performance of the control system, the poor steadystate effects and other issues.Based on the permanent magnet synchronous motor current state equations derived, the deadbeat control in place of current loop PID controller. LabVIEW was designed based on the following permanent magnet synchronous motor speed PC monitoring software, send and receive data, the entire permanent magnet synchronous motor speed to be monitored during the experiment, reducing the experimental cost and easy to store data. Experiments show that the monitoring software can accurately observed experimental data, effectively replaced the oscilloscope, and successful validation of the permanent magnet synchronous motor vector control algorithm.
Key words: PMSM; vector control; monitoring software
