Application Research of section map CMAC neural network for Linear Servo System

A new method for section concept map was proposed for CMAC. It can remedy the defects of the traditional concept map method. Higher dimensional vector map algorithm and formula was derived on base of one-dimensional and two-dimensional vector map. The method allocates virtual address and storage space dynamically, and divides the virtual address into sections according to receptive field. To analyze performance of the method, a modeling analysis for PMLSM was performed on the space-vector control scheme, and a servo control system was developed. Experiments were carried out. The results show that the section map CMAC improves dynamic response performance and disturbance rejection ability, and reduce the static error compared with the PID method. Also, the system has a superior generalization and application value.
