摘要

感应电动机是工业领域中非常重要的部件。本文提出了采用直接转矩控制(direct torque control, DTC)控制器的1M异步电机变速作动器，通过自适应算法实现对磁链和转矩的同时控制，提高了DTC控制器在运行全过程的效率。该自适应算法在运行启动阶段设置较大的转矩和磁链来补偿不稳定性，同时设置较小的转矩和磁链来控制稳态运行。变速驱动器通过改变IM电源的电压和频率来控制IM的转速和转矩，在控制IM的转速和转矩方面起着至关重要的作用。通过数字信号处理器(DSP) ZQ28335的仿真和实验结果保证了转矩和磁通运行时准确的动态响应。

DTC Controller Variable Speed Drive of Induction Motor with Signal Processing Technique

Induction motors (IMs) are very important components in industrial fields. This paper, variable speed actuator of induction motor (1M) with direct torque control (DTC) controller is proposed to control both flux and torque to increase the efficiency of a DTCIM in all period of operation due to adaptive algorithm. This adaptive algorithm set a large torque and flux at starting stage of operation to compensate instability while the small values of both torque and flux to control the steady state operation. Variable speed drive (VSDs) plays very essential role to control the speed and torque of IM by varying the voltage and frequency of IM supply. Simulation and experimental results through digital signal processor (DSP) ZQ28335 ensure accurate dynamic response in the torque and flux operations.
