基于DCS系统的热水锅炉模糊PID控制系统

结合某热力公司46MW热水锅炉的燃烧控制改造工作,在DCS系统中,以锅炉出水温度为被控量,对锅炉炉排引入模糊控制与经典PID结合构成的复合模糊PID控制器进行出水温度的控制,解决了外界气温变化与锅炉燃烧实时调节的矛盾,实现了按需供热.

System of Hot Water Boiler Fuzzy-PID Control Based on DCS

This paper companies thermal heat Center new 46MW hot water boiler combustion control design work.In the DCS system,the boiler water temperature is charged Variable.In the grate boiler with the introduction of fuzzy classic PID control with a composite fuzzy PID controller Water temperature control and resolve the outside temperature changes and real-time adjustment of boiler combustion contradictions and realized the heating on demand.
