| 摘 要： | 以传动系统试验台为研究对象,在研究异步电动机直接转矩控制Direct Torque Control(DTC)的基础上,提出在传动系统试验台上实现电机四象限工作的DTC过程,并用Matlab/Simulink进行了仿真实现.设计出的控制系统根据定子磁链状态矢量进行空间进行定位,通过对扭矩和磁通的简单继电式方式比较,配合开关选择表策略,成功实现了对异步电动机转矩和转速的直接转矩控制,为将DTC技术应用于传动系统电机智能控制的实际工程奠定了基础.

| Abstract: | The transmission system test platform is studied.Based on the principle of direct torque control (DTC) for asynchronous machine,the process of the machine operating in four axis coordinates is proposed,and Matlab/simulink software is used for simulation analysis.The mathematic model of asynchronous motor is established under d-q coordinates for the designed DTC controller. Although the torque,flux and flux magnitude are all controlled by a hysteresis comparator.Based on the designed simple switch select tab... |
