speed negative feedback meaning in Chinese

速度负反馈

The third , the paper analyses and expatiates three mode of speed regulating which are speed negative feedback , voltage negative feedback and voltage negative feedback plus cuttent positive feedback and designs a speed regulating control system adopting the mode of voltage negative feedback plus cuttent positive feedback . at the same time we optimize the speed regulating system using the appraisal software of the performance of wire feeder
再次,从控制论的角度对转速负反馈、电压负反馈、电压负反馈配合电流正反馈等三种转速调节方式进行了分析论述,采用电枢电压负反馈配合电流正反馈方式设计了送丝机调速控制系统,并采用送丝机性能评估软件对调速系统进行了优化。
