摘要：无轴承同步磁阻电机运行控制系统中，须使用相关传感器检测出电机转速和位置信号，然而传统机械式传感器的安装与使用不仅使电机体积增大、成本增加，难以准确检测高速度，限制了无轴承同步磁阻电机高速运行使用场合。为实现无轴承同步磁阻电机高速超高速、低成本、实用化运行，提出了一种基于锁相环法的无速度传感自检测技术。通过应用锁相环原理，设计出无轴承同步磁阻电机无速度传感器，并基于Matlab/Simulink仿真软件构建无轴承同步磁阻电机控制系统，对所提理论进行仿真实验研究。仿真结果表明：该方法可实现对转子位置/速度信号进行实时有效辨识，从而验证了该方法的可行性。

Abstract: n the control of bearingless motor, sensor should be used to detect rotor speed and position signal. However, installation of traditional mechanical sensor increases the size, cost and detects inaccurately in high speed of motor and limits the motor working occasion of a high speed. In order to realize the high and ultrahigh speed, low cost, and practical operation of bearingless synchronous reluctance motor, a novel rotor position and speed estimation scheme using phaselocked loop(PLL) was proposed. By using the principle of phaselocked loop, a speed sensorless of bearingless synchronous reluctance motor was designed. And based on Matlab/Simulink software, the bearingless synchronous reluctance motor control system was built to verify the proposed theory. Simulation study demonstrates that the proposed method is able to estimate rotor position/speed precisely and the feasibility of the method has been verified.
