摘　　要：永磁同步电机(PMSM)在有感控制方案中需安装编码器或霍尔传感器,增加了系统的设计成本,因此,研究PMSM的无感控制方案就显得有必要性。随着现代控制理论的发展,无传感器技术也日益发展。以磁场定向控制为控制策略,以模型参考自适应理论为基础,设计了一种速度观测器。侧重用现代控制理论知识分析了观测器的稳定性,并用传统控制理论知识分析了一种新的观测器中PI调节器参数整定方法。这种方法具有很强的适应性和移植性。最后,验证了这种方法的准确性和可行性。In sensor control, permanent magnet synchronous motor need install encoder and hall sensor, this will undoubtedly increase the cost of the system design. So, it is necessary to study on sensorless control. With the development of modem control theory, sensorless technology was also growing development. The control strategy was based on field oriented control, and then a speed observer was designed based on model reference adaptive theory. The stability of the observer using the knowledge of modem control theory was analyzed, and a new method for adjusting the parameters of PI using the knowledge of traditional control theory was analyzed. This method has a strong adaptability and transplantation. Finally, the accuracy and feasibility of this method were verified.
