异步电机三电平矢量控制传动离线自整定

Off-line Parameter Identification of Induction Motor on the Structure of Three-level Inverter Vector Control

从异步电动机的状态方程出发,通过静止状态下对状态方程的简化和变形,采用特殊信号激励方法,对异步电动机三电平矢量控制系统进行离线参数估计,为传动系统调节器参数设计和参数在线估计做基础,仿真和实验结果验证了方法简单有效。

Based on equations of the state, the selfcommissioning of induction motor is implemented on the structure of three-level inverter vector control at the stand still by specific signal prompting and the basis of PI regulator and on-line parameter estimation is established. The validity of the proposed method is demonstrated by the simulation and experiment results.
