摘要
研究基于矩阵变换器直接转矩控制系统应用无速度传感器技术以及将三者融合的技术。仿真结果表明参数辨识的精度高于测量模块的测量精度,动态响应好。在电机加减速运行和负载转矩变化时,系统能够实现转矩和磁链的控制要求,系统运行稳定,矩阵变换器能够实现能量双向流动和输入单位功率因数。
In this paper the speed sensorless technology based -on matrix converter（MC） direct torque control system （DTC -MC）and their fusion technology were studied. Simulation results showed that accuracy of parameter identification was higher than measurement accuracy of measuring module, and dynamic response was also fast. The system not only can realize the control request of torque and flux linkage as speed or load torque of AC motor changed, but also operate steadily, matrix converter can actualize energy bidirectional flow and import unity power factor.
