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.
