摘要
直接转矩控制是通过转矩与磁链控制来控制电机的一种方法。本文在对感应电动机的数学模型进行分析的基础上,基于Matlab/Simulink仿真计算,设计了直接转矩控制系统的磁链计算以及磁链和转矩控制模块,构建感应电动机直接转矩控制系统仿真方案,并通过仿真结果,分析了转矩、控制器参数和磁链滞环容差变化对控制系统的影响,证明了所建模型通过磁链与转矩的计算实现了感应电机转速的直接转矩控制。
Direct Torque Control is a method to control machine with utilizing torque and flux of motor controlled.Based on the model of induction motor and the calculating of MATALAB/Simulink,Flux module and delay of torque module are designed,a method for modeling and simulation of DTC system is build to analyze the influence by change of the load torque,the control parameter,and the tolerance of flux,and simulations confirm that the method of direct torque control system is realized by calculate the flux and torque.
