永磁同步（PM）电机广泛用于工业应用。在永磁电机驱动系统中，由于永磁电机的磁场不可控，无法进行弱磁控制，难以实现牵引电机和主轴电机的宽转速恒功率运行。然而，由于d轴电枢反应（弱磁控制），气隙磁通可以被消磁效应削弱。本文提出了一种内置式永磁电机的宽转速控制方法，包括最大转矩电流比控制和弱磁控制。在高速弱磁区，由于电流调节器的饱和和磁饱和的影响，会出现控制性能变差、控制系统不稳定的情况。提出了补偿这些影响的高性能电流调节器。所提出的控制系统的控制性能被证实的几个驱动器测试与原型IPM电机。
Permanent magnet synchronous (PM) motors are widely used for industrial applications. In the PM motor drives, it is difficult to achieve the wide speed and constant power operations, which are desired in traction and spindle drives, because the field-flux of PM motor is uncontrollable and as a result the field-weakening control is not available. The air-gap flux, however, can be weakened by the demagnetizing effects due to the d-axis armature reaction (flux-weakening control). In this paper, the wide speed control method of the interior PM (IPM) motor, which includes the maximum torque-per-ampere control and the flux-weakening control, is proposed. In the high-speed flux-weakening region, there are some cases where the control performances become worse and the control system becomes unstable because of the saturation of current regulator and the effects of magnetic saturation. The high performance current regulator compensating these effects is also proposed. The control performances of the proposed control system are confirmed by the several drive tests with respect to the prototype IPM motor.
