摘要
在矢量控制和直接转矩控制的基础上 ,取长补短 ,提出一种新型的感应电动机按定子磁场定向控制的方法 ,采用定子电阻压降补偿和电流转矩分量的闭环控制 ,实现了定子磁链和电磁转矩的协调控制。实验结果表明 ,该方案完全可行 ,系统具有良好的静。
A new control strategy of induction motors with stator flux orientation that combines the advantages of both Vector Control and Direct Torque Control is presented.According to the dynamic model of induction motors,stator flux and electromagnetic torque are controlled respectively.The main contribution is to control differential of stator flux by compensating voltage drop of stator resistance.The conclusions of theoretical analysis and experimental research can be summarized as follows:①Rotor parameters are not appeared in the control law,which enhances robustness of the system;②Continuous control is used to avoid torque ripple which is inevitable in bang bang control.
