| 摘 要： | 在线性自抗扰控制技术基础上，引入解耦补偿器，提出汽包锅炉单元机组协调系统的新控制方案。该方案首先对单元机组设计解耦补偿器，进行一定程度解耦；再将其他通道耦合作为扰动，分别设计炉侧和机侧线性自抗扰控制器，进一步消除耦合的影响。由于线性自抗扰控制技术采用扩张状态观测器，可以对扩张状态（系统未建模动态摄动和未知扰动1进行在线实时估计，因此其设计的扰动补偿可以不依赖于模型达到快速消去扰动的效果。将该方法应用于一500MW汽包锅炉单元机组协调系统进行仿真研究，结果表明该方案可以实现良好的动静态解耦，有较强的鲁棒性和抗干扰能力，并且算法简单、调试容易。

| Abstract: | A novel scheme for the coordinated control of drum boiler-turbine units was presented based on the principle of linear active disturbance rejection control(LADRC) and decoupling compensator.A decoupling compensator was designed based on a simplified linear boiler-turbine model which captured the essential dynamics and interaction of a unit,then LADRCs for boiler and turbine were designed separately to further reduce the coupling by taking it as disturbance.Since LADRC estimated real-time disturbance via ext... |
