Design and Realization of the PLC control system in Automobile dust cover of transmission shaft experimental rig

This article introduces the successful application ofPLC and Frequency converter in the high- low temperature con-trol system of dust cover of transmission shaft of the automobile,And it introduce the system design philosophy and Structure ofthe software and hardware, Especially it introduce the tempera-ture predicts that is suitable for being accused of the target forpure two steps of inertia link that lag behind. This algorithm issuperior to routine PID algorithm. The systematic function isstrong , of good performance, the precision is relatively high.
