矢量控制感应电机速度伺服系统一般都有电机电压和电流的限制。当速度伺服系统具有大转矩参考时，其PI控制器的输出常常饱和。在这种情况下，常规伺服系统停止其PI控制器的积分计算。然而，这种系统往往有一个大的超调和/或振荡的响应所造成的饱和现象和相位误差的矢量控制条件。提出了一种考虑电压饱和的矢量控制异步电动机速度伺服系统。该控制方法能够快速补偿矢量控制条件下的相位误差，并始终保持矢量控制条件。实验结果表明，所提出的系统可以很好地调节电机的速度和电机的次级磁通的大转矩参考，而没有饱和现象。
Generally, a speed servo system of vector-controlled induction motor has a limitation of motor voltage and motor current. When the speed servo system has a large torque reference, the output of its PI controller is often saturated. In this case, the conventional servo system stops the integral calculation of its PI controller. However, this system often has a large overshoot and/or an oscillated response caused by both a windup phenomenon and phase error on vector control condition. This paper proposes a new speed servo system considering voltage saturation for vector-controlled induction motor. The proposed control method compensates the phase error on vector control condition quickly, and always keeps the vector control condition. The experimental results show that the proposed system well regulates a motor speed and a motor secondary magnetic flux for a large torque reference without a windup phenomenon.
