摘　　要：针对普通无速度传感器矢量控制算法无法满足永磁同步电机(PMSM)高速运行问题,设计了一种基于模型参考自适应系统(MRAS)的矢量控制方案。该方案由I/F控制器和MRAS控制器组成。低转速采用I/F控制器控制电机转速,高转速采用MRAS控制电机转速,特殊处理后使切换过程中电流平滑过渡,以达到高低转速均可正常运行的目的。以磁悬浮PMSM作为驱动对象,电机转子联接风机实现带载。试验结果表明,与传统的无传感器矢量控制相比,所提出的控制方案更有效地驱动PMSM,满足高速运行工况。The traditional speed sensorless vector control algorithm cannot meet the high-speed operation of the permanent magnet synchronous motor(PMSM).In order to solve this problem,a vector control scheme based on model reference adaptive system(MRAS)is designed.The control scheme is composed of an I/F controller and a MRAS.The I/F controller is used to control the motor at low speed and the MRAS is used to control the motor at high speed.After special treatment,the current in the switching process is smoothly transited to realize the normal operation at high and low speeds.The magnetic levitation PMSM is used as the driving object,and the rotor of the motor is connected with the fan to realize loading.The test results show that,compared with the traditional speed sensorless vector control,the proposed control scheme drives the PMSM to meet the high-speed operation conditions more effectively.
