摘要
直接转矩控制是一种高性能的交流传动控制策略,无速度传感器控制的研究代表了直接转矩控制系统的一个发展方向。在直接转矩控制理论基础上,推导出一种基于定子磁链矢量增量来确定定子参考电压矢量的新型无速度传感器直接转矩控制方案。该方案还能对转矩和磁链实现良好的控制功能。计算机仿真结果证明了方案的可行性。
Direct torque control is a new-style control technique of AC driving. Speed sensorless control is one of the most important directions of development for DTC. This paper obtains a new speed-sensorless direct torque control scheme for induction motor based on calculating the stator flux vector increment to determine the stator reference voltage. This scheme can also reduce the torque and flux ripples with a good dynamic and static performance. Computer simulations show its effectiveness.
