  • A lot of synchronous radiate heat is generated when beijing electron positron collider operating. The heat is dissipated by the beam pipe’s cooling system. According to the key problem of cooling the beam pipe, an active cooling system based on modular form was developed. In order to investigate the cooling system, a dynamic model was established and flow characteristics equations were derived from parallel regulator valves, by means of lumped parameter method with physical analysis and logical simplification. A fuzzy control strategy was offered and simulated according to the model. Simulation results indicate that the cooling system with fuzzy controller can satisfy the system design demands. It is demonstrated that the fuzzy control strategy is more stable and less overshoot than conventional proportional-integral-differential control strategy. The results can also instruct the engineering design.
