Considering the inconvenience of regulation and difficulty of parameter tunning as AC servo system in practical situation, three ways of intelligent control approach to realize auto-tuning and autorecognization of AC servo system, are proposed, which is a robust controller based on two-degrees-offreedom with no tuning to controller, a auto-tuning controller based on fuzzy reasoning with no inertia recognization but tuning parameter of controller, a strategy recognizing inertia of servo system and tuning parameter or structure of controller automatically. In the same time, these control strategies are analyzed from the theory and reliability. The comparative analysis of three measures on strong and weak points is made by simulation and experiment results.

针对交流伺服系统在实际应用中存在的系统调试不便、参数调整困难等问题，提出了实现交流伺服系统自调整和自识别等智能化控制策略的三条途径：一是具有控制器无调整特点的二自由度鲁棒性控制器；二是惯量无识别但需自动调整控制器参数的模糊推理自调整控制器，三是自动识别伺服系统转动惯量并自动调整控制器参数和结构的方案，从理论分析和可实现性两方面对这些控制方案进行了论述，并通过仿真和实验研究，对比分析了各种方案的优缺点，得到了一些有益的结果。
