摘要

提出了一种利用直接转矩控制(DTC)方法控制变频感应电机占空比的方案。与传统的直接转矩控制相比，采用占空比控制实现了更好的稳态转矩响应，且转矩脉动较小。采用模糊逻辑控制，以转矩和磁链误差作为输入，实现每个开关周期的占空比。利用SIMULINK进行了仿真，验证了所提出的要求。

Torque ripple minimization in direct torque control of induction machines

A duty ratio control scheme for inverter-fed induction machines using the direct torque control (DTC) method is presented. An improved steady state torque response was achieved using the duty ratio control and had shown less torque ripple compared to the conventional DTC. Fuzzy logic control has been used to implement the duty ratio during each switching cycle using the torque and flux errors as inputs. Simulation results using SIMULINK gave results that justify the claims.
