| 摘 要： | 研究了基于交流异步电机的伺服系统的鲁棒性设计问题。在采用频率响应法辨识出异步电机模型参数的基础上，利用干扰观测器对交流伺服系统中由模型参数变化、载荷改变等产生的干扰加以估计，并将其作为补偿信号反馈到输入端。研究表明采用干扰观测器的交流伺服系统具有较强的鲁棒性。

| Abstract: | The robustness design of AC servo system based on induction motor was discussed in this paper. Based on the parameters that identified by frequency response method, a disturbance observer was used to estimate the disturbance generated by the variation in model parameters and load in AC servo system. Then the estimation was fed back to the input channel as a cancellation signal. It was proved by the research that the AC servo system adopted by the disturbance observer can provide strong robustness. |
