Based on describing the constitution and work principle of SUPCON WebField JX-300X DCS,this paper discussed the control process of the system in Baota gas-fractionation,expounded further the advance of the control system and importance of the serial control.

A scheme of design of composite fuzzy serial control system is presented keeping the anti jamming function of serial control and the good dynamic characteristic of fuzzy control based on the analysis of the characteristic of superheated steam temperature of thermal power station.

The PID series control algorithm with generalized forecasting compensation-autocorrection has been adopted in the temperature controling system of quenching and ageing stores for the heat treatment of aluminium alloy after its moulding.

It uses SCM as the primary computer, and through the series control it realizes to control those objects having the nature of large time-delay in the sense of software designs,it uses the thought of modularization and adopts C language for the application program of SCM.

The good result could be achieved by using the PID series control and adjusting PID Parameters.

This paper analyses the steering gear of valve-pump parallel cont rol, the s teering gear of valve-pump series control, the steering gear of electronic-hydr aulic complex control from angle of technique hydraulic complex control.
