The necessity and functional requirement of aircraft cooperative development is presented firstly,and the function of Avidm in constructing the platform of cooperative development among different departments is introduced.

The basic principle of water pollution synergetic control;

Design of TCSC cootroller based on synergetic control theory;

This system applies to the double wire pulsed MIG welding system as the communication platform of cooperation control,it makes the current output of welding power supply with the pulsed pattern,and phasic discrepancy of 1 800,at .

On the basis of analyzing the demand of cooperation and group awareness in Computer Supported Cooperative Work, the topology of shared whiteboard is proposed, and the design of the shared object and cooperation control in this environment is described.

Based on the robust control theory,the cooperation control methods between node companies in a closed-loop supply chain(CLSC) networks are studied.

Based on the soft-switching power supply and by applying the CAN bus technique, a synergic controlled Tandem twin-wire high-speed welding equipment was developed.

,a compacted,integrative and synergic controlled tandem equipment is designed.

From the viewpoint of synergic control, a microcomputer control system of pulse MIG welding is developed in this paper, and the hardware structure and control principle of the system are introduced.
