| 中文摘要 |
| 循环流化床锅炉燃烧系统是典型的具有非线性、大滞后、强耦合特性的系统, 很难建立准确的数学模型,常规的控制方法难以取得良好的控制效果. 自抗扰控制器具有结构简单, 不依赖被控对象具体模型等优点, 易于工业现场应用. 本文为某国产75 t/h循环流化床锅炉燃烧系统设计自抗扰控制器, 使用非支配排序果蝇算法对控制器参数进行基于ITAE指标、调节时间和最大控制量的多目标优化. 用所设计控制器进行仿真研究, 并与非优化的自抗扰控制器和基于预期动态的PI控制器进行比较. 结果表明, 所设计控制器效果最优, 可以更有效地对通道间的耦合
进行估计和补偿, 具有更强的解耦能力. |
| 英文摘要 |
| In this paper, the control of circulating fluidized bed boiler (CFBB) combustion system is studied. CFBB is a nonlinear system, which has large time delay and coupling and is difficult to establish accurate mathematical model. Therefore,
conventional control method can hardly achieve effective control. The active disturbance rejection controller(ADRC) has simple structure and does not rely on accurate model of plant. In this paper, ADRC is designed for a domestic 75t/h CFBB. Multi-objective optimization algorithm(non-dominated sorting fruit fly algorithm) is applied to optimize the controller parameters using the ITAE index, the response time as well as the maximum of the control energy. Simulation results show that the optimized ADRC can effectively estimate and compensate the loop coupling, leading to the strong decoupling
ability. |
