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.
The direct torque control method based on voltage vector was selected to control the torque ripple. The voltage vector controller adopts bang-hang hysteresis control. The ob- server of flux linkage can be estimated online and to be im- proved 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 identifica- tion method by adaptive neural network. Simulation and ex- periment 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.
