| Abstract: | A digital PWM wire-feeding timing system with DSP is designed,an inverse feedback control method of induction voltage is introduced.Based on traditional PI control and fuzzy control,a new fuzzy PI controller is investigated to realize the online regulation of rotate speed.It is proved by tests that the wire feeding system with the better characteristics of dynamic and static,and the linearity is also better than others,especially when the load changes in short time,it can response rapidly,which can satisfy ... |
