摘要:
为减小无刷直流电机的转矩脉动,提高其动态性能,提出了一种将直接转矩控制和模糊控制相结合的方法。直接转矩控制响应迅速,但转矩脉动相对较大,为了减小转矩脉动,设计了一种基于模糊数理论的模糊控制器。该控制器根据转矩和磁链的偏差选择适当的电压矢量,并根据转矩偏差和转矩偏差的变化率,采用模糊自调整因子的方法模糊预测电压矢量作用时间,从而有效地减小了转矩脉动并保持了直接转矩控制响应快的优点。利用MATLAB对所提出的方案进行了仿真,采用TI公司的TMS320LF2407进行了实验。结果表明,与传统方法相比,该方法有效地提高了无刷直流电机的稳态和动态性能。
Abstract:
In order to minimize torque ripple and improve dynamic performance of brushless DC Motor(BLDC),a scheme that combines direct torque control(DTC) and fuzzy control is proposed.DTC has the advantage of fast response,but its torque ripple is relatively high.To reduce the torque ripple,a fuzzy controller based on the fuzzy number was designed.The correct voltage vector was selected according to the torque error and stator flux-linkage error,and according to the torque error and error variance ratio,the active t...
