冷凝器真空压力模糊PI控制系统

摘要

This paper analyses the occurring reasons of condenser pressure and the factor that affect it, it designs the condenser pressure control systems in different situations by the method of fuzzy PI. Through the simulation, it shows that fuzzy PI controller has a better performance on condenser pressure control than traditional PI controller.%分析冷凝器真空形成的原因以及影响真空稳定的因素,通过模糊PI的方法设计出冷凝器在不同工况下的真空压力控制器.通过仿真表明,模糊PI控制器较之常规PI控制器,对于冷凝器真空压力的控制性能更好.
