锅炉控制系统可以分为汽包水位控制系统、蒸汽压力控制系统、炉膛负压控制系统和燃烧经济控制系统。
Boiler control system is composed of drum water level control system, stem pressure control system, hearth negative pressure control system and combustion economical control system.
火电厂炉膛负压控制系统中有时含死区类的强非线性环节，死区使该控制回路产生振荡，仅用常规pid控制器无法克服这一现象。
Sometimes the negative pressure control system of boiler in power plant contains a strong nonlinear sector such as dead-zone which makes the system oscillate.
同时也介绍了送风量、炉膛负压和一次风量的控制。
Meanwhile, the control of air flow, furnace negative pressure and primary air flow are introduced.
汽包水位、蒸气温度、炉膛负压的控制采用模拟调节方式，其中汽包水位则选择了模糊PID调节。
The controls for drum water level, steam temperature, and negative furnace pressure are in analog control, among them, the drum water level control is under fuzzy PID control.
处理后的数据参与控制运算，实现流化床床层温度、炉膛负压、烟气含氧量等控制回路的自动调节功能。
The system uses intelligent PID controller to design automatic control loops, including pressure of incinerator, percentrage of oxygen in gas.
