摘要
针对超临界机组除氧器非线性、大迟延、强耦合和模型时变特性,传统的PID调节器难以使除氧控制系统达到理想的控制效果。为了对除氧器水位和凝泵出口压力的控制取得满意的效果,采用自抗扰控制技术(Auto Disturbance Rejection Control)。通过仿真表明,用ADRC控制器控制除氧系统具有较好的解耦效果、较快的响应速度和较强的抗干扰能力。
Deaerator nonlinear,large delay,strong coupling and model time-varying characteristics,the traditional PID regulator oxygen control system was difficult to achieve the desired control effect in the supercritical unit.In order to deaerator water level and the condensate pump outlet pressure control to achieve satisfactory results,using Auto Disturbance Rejection Control(ADRC) technology.The simulation shows that the strategy has a good decouple,quick response and disturbance rejection properties,we control the deaerator using ADRC(ADRC) in the design.
