| 摘 要： | 在三相交流调速系统中，整流侧采用空间电压矢量控制技术可以实现整流环节网侧电流正弦化，运行于单位功率因数，且能实现能量的双向流动。整流器和逆变器均采用全控型器件，器件工作在高频状态。文中采用模型参考自适应（MRAS）技术对三相交流异步电机的转速和磁链进行观测，并采用基于指数趋近律设计方法的滑模速度控制器来代替传统的速度控制器，通过MATLAB仿真研究，加入滑模控制，增加了调速系统负载的抗干扰性，提高了系统的响应速度，使得系统运行更加稳定。

| Abstract: | In the three-phase AC Speed regulationtechnology, the system can realize the rectifier gridsystem, rectifier uses the voltage space vector controlside current sinusoidal, run in unit power factor, andcan realize the two-way flow of energy. Rectifier and inverter adopt full controlled devices, the deviceworks in high frequency. In this paper, the model reference adaptive （MRAS） speed and flux of three-phase AC asynchronous motor is observed, and the speed controller with sliding mode speed controller isdesigned based on the exponential reaching law method to replace the traditional, through the simulationof MATLAB, adding sliding mode control, can increase the speed of system load disturbance resistance,improve the system＇s response speed, and make the system more stable. |
