| Abstract |
This new control system for the AC induction motor is extremely simple. It creates "natural field orientation'' with "decoupling" and "quadrature" at all speeds, thanks to voltage control. Voltage control is considered to give slow response. However, measurement of the transient torque response shows that a standard industrial motor has surprisingly fast response. The response time can be shortened by signal shaping networks. A theoretical comparison with current control is made. Torque linearity and torque ripple is studied. An exact mathematical analysis of the control system is made. The development work has been supported by the National Swedish Board for Technical Development. |
