Abstract: Brain emotional learning(BEL) model based intelligent controller for a turntable servo system with high precision is presented.BEL model is a bio-computational model inspired by the emotional learning mechanism in mammalians brain.BEL based intelligent controller is designed by fusing the information of system tracking error,control variables and etc.Different control structure can be designed by selecting different sensory input signals,and controller parameters are adjusted by online learning the nodes weights in BEL model based on an associative learning method,and then the adaptive tracking control of the turntable servo system is realized.Simulation and experimental results show that the BEL based intelligent controller has strong learning ability,and can restrain the nonlinear factors such as friction,and exhibits good stability and high tracking precision in application of the real-time control system.
