摘要

采用基于电压矢量的直接转矩控制策略对转矩进行控制,电压矢量控制器采用Bang-Bang滞环控制,磁链观测器采用在线估算同时提高定子电压、电流测量的精度以提高磁链精度,转矩观测器采用自适应神经网络的智能辨识方法获得瞬时转矩.仿真和实验结果表明,直接转矩控制策略在保证电机可靠运行的前提下,实现了转矩在一定范围内的恒定,一定程度上有效抑制了转矩脉动.

Abstract

The direct torque control method based on voltage vector was selected to control the torque ripple. The voltage vector controller adopts bang-bang hysteresis control. The observer of flux linkage can be estimated online and to be improved at the same time through enhancing the measurement accuracy of voltage and current. As for torque observer, the instantaneous torque can be got through intelligent identification method by adaptive neural network. Simulation and experiment results show that the direct torque control method not only can ensure SRM reliable operation and the constant torque, but also can restrain torque ripple effectively to some degree.
