Application of Cerebellar Model Articulation Controller (CMAC) with a Modified Algorithm in Monitoring Machine Performance Degradation

摘要

On the basis of CMAC-PDM (Pattern Discrimination Model) , a novel algorithm of CMAC for monitoring machine degradation is proposed in this paper. The output of CMAC with the novel algorithm represents the state of a machine and PDM is not needed. The principle was explained by analyzing the modified mapping process of CMAC. The novel CMAC is applied to a tool condition monitoring system and two methodologies (novel CMAC and CMAC-PDM) are compared. The results prove that the novel algorithm is feasible and its computational complexity is reduced significantly.
