Adaptive control technique can send control objects and operation

Adaptive control technique can send control objects and operation condition change the performance of

the control system,N.M atsui,J.H.L ang et adaptive control technology was applied to permanent magnet

synchronous motor 220v ac electric motor sspeed control system.Simulation and experimental results show that the adaptive control technique can make the speed regulation system in the motor parameters change to keep good performance.Sliding mode variable structure control due to its special way of"switch"to control and motor speed control system of inverter are of a similar"switch"model and has good robust control properties,therefore,has a broad application prospect in the field of motor control. Online identification through change of motor parameters,and using the identification parameters for control of www.facebook.com/guohong.trading the speed regulation system,can improve the robustness of control system.

With the development of artificial intelligence technology,intelligent control has become an important branch in the field of modern control,used in electric drive control system of intelligent control technology has become induction motor price the main direction of electrical drive control,and will bring a new era of electric drive technology.At present,the effective ways to realize the intelligent control has three: based on the expert system of artificial intelligence (ExpertSystem);Fuzzy control based on fuzzy set theory (FuzzyLogic);Based on artificial neural network (Artificia1NeuraNetwork) neural control.B.K.B ose and others from the late eighty s,has been committed to the application in the field of artificial intelligence technology in 220v ac electric motors the electric transmission,and achieved gratifying results.
