The Application Of Fuzzy-Neural Network In AC Servo System

In this paper,alternating servo system with high performance was studied。According to the characteristic of this kind of system,it has a wide range and time－varing the rotating inertia and very strong interference moment,all this can change the parameters of the system in wide range。To the traditional control methods,it's difficult to obtain the satisfied dynamic characteristic。In this condition,we propose a new control method－PID control,fuzzy control,fuzzy—PID and fuzzy neural control algorithm respectively。And using this controller,simulations were done on the system。The results of simulations and experiments show that this fuzzy－neural network controller has very strong self－adaptive and robust。It can effectively inhabit the mal－conditions caused by the load change and serious disturbance,and satisfy the requirement of the servo system completely。...
