摘要: Traditional direct torque control system of induction motor introduces conventional PI regulator in speed loop, it is proved that the low precision debases performance whole system. This paper establishes a fuzzy regulator, which applies principles and method logic to adjust proportional coefficient k/sub p/ integral 1/ on-line, finally get adapt different variations. The proposed implemented with single board microcomputer uses TMS320LF2407A DSP. experimental results show can ensure swift response, small overshooting, high steady both speed. Additionally, improves observation stator flux enhances robustness
