中文摘要：

根据交流伺服系统的控制性能评价需求，在综合比较了ISE，IAE，ITAE等性能评价指标的特性后，设计了一种IITAE（改进的ITAE指标）作为伺服系统的控制性能评价指标，利用该指标设计了基于坐标轮换算法的伺服控制参数自整定模型，并进行了实时仿真研究，结果表明：IITAE性能评价指标具有较好的适用性，坐标轮换算法是获取伺服系统优化控制参数的高效途径。

英文摘要：

According to the needs of the assessment of AC servo system control performance, after a comprehensive comparison of the characteristics of performance evaluation indicators such as ISE, IAE, ITAE, etc. a IITAE （improved indicators ITAE） as a servo system control performance assessment method was designed, which was used to design the servo control parameter self-tuning model based on the Coordinate rotation algorithm and a real-time simulation was conducted. The results show that： The IITAE performance evaluation index has good applicability and coordinate rotation algorithm is an efficient way to get optimal control parameters of the servo system.
