| Abstract: | In order to make a manipulator track the target trajectory accurately and get good real-time performance,an improved RBF fuzzy neural network algorithm is put forward.This algorithm uses a novel fuzzy genetic algorithm to regulate the parameters of fuzzy controller and the parameters are optimized.Simultaneously the nearest neighbor clustering algorithms are used to refresh the fuzzy rules.In the simulation,compared with traditional fuzzy algorithms,this improved algorithm gets better performance,learning speed,high precision tracking and has good control performance and self-learning ability. |
| Keywords: | trajectory tracking Radial Basis Function Neural Network（RBFNN） Fuzzy Genetic Algorithms（FGA） Nearest Neighbor Clustering Algorithms（NNCA） |
