针对循环流化床（CFB）锅炉火电机组复杂的非线性和大惯量性能导致现有PI型负荷-燃料控制回路无法正常工作的问题，提出了一种新型的两层分层Takagi-Sugeno模糊双曲正切静态模型控制方案。在上层，开发了一种采用 Takagi-Sugeno 模糊双曲正切静态模型控制算法的参考调速器，以对下层现有 PI 型负载-燃料控制回路的外部负载命令进行补偿。通过构造新的二次积分Lyapunov函数，推导了所提出的控制系统的稳定性条件。在CFB锅炉分散控制系统(DCS)中实现时，构建了参考调速器，并采用三次变量双曲正切函数算法，可以有效对抗非线性和大惯量性能。实验结果表明，提出的分层模糊双曲正切静态模型控制方案能够明显提高PI型负荷燃料控制系统的控制性能，明显减弱主蒸汽压力和床温的波动，使受控系统更加稳定。
This paper proposed a novel two layer hierarchical Takagi-Sugeno fuzzy hyperbolic tangent static model control scheme for a circulating fluidized bed (CFB) boiler thermal power unit to cope with the complex nonlinearity and large inertia performance which make its existing PI type load-fuel control loop not functioning normally. In the upper layer, a reference governor with Takagi-Sugeno fuzzy hyperbolic tangent static model control algorithm was developed to yield a compensation for the external load command of the existing PI type load-fuel control loop in the lower layer. By constructing a new quadratic integration Lyapunov function, the stability condition of proposed control system was derived. While implemented in the decentralized control system (DCS) of CFB boiler, the reference governor was constructed and adopted the cubic variables hyperbolic tangent function algorithm which can oppose effectively the nonlinearity and large inertia performance. The experimental results shown that the proposed hierarchical fuzzy hyperbolic tangent static model control scheme can improve the control performance of the PI type load-fuel control system obviously, weaken the fluctuation in the main steam pressure and bed temperature apparently and make the controlled system more stable.
