本文讨论工业规模填充床反应器的低阶输出调节器设计。在基于静态插值技术的数据协调机制下，基于最优的双输入控制方案通过利用次级输出信息几乎可以衰减初级输出上的可测量干扰。稳态方法不仅减少了临界热点和/或热失控，而且还主导了出口中的期望转化率。此外，分段迭代过程与可行的规划进化控制计算的建议，使灵活的输出调节器与“智能”算法的帮助下，可以有效地提高瞬态性能。仿真结果表明，非分布式，分段反馈控制方案是对未知扰动的鲁棒性。
This article deals with the low-order output regulator designs for a commercial-scale packed-bed reactor. Under the static interpolation-based technique for data reconciliation mechanism, the optimum-based two-input control scheme by exploiting the secondary output information can almost attenuate measurable disturbances on the primary output. The steady-state approach not only reduces the critical hot spot and/or thermal runaway but it also dominates the desirable conversion rate in the exit. Moreover, the piece-wise iterative procedure connected with feasible programming evolution for control computation is proposed such that the flexible output regulator with the aid of the ‘intelligent’ algorithm can effectively improve the transient performance. Simulation results have shown that the non-distributed, piece-wise feedback control scheme turns out to be robust against unknown perturbations.
