Abstract :
In this paper, we proposes a direct torque control method of alternating current servomotor, which aims for solving the problems such as large torque ripple of direct control in low speed range and inconsistent inverter switching frequency. In the thesis, SVPWM control strategy and fuzzy neural network adjustor are used for controlling. MATLAB simulation proves that the asynchronous motor using this type of control has small torque ripple and good performances both in dynamic and static.
