| 中文摘要 |
| 针对化工过程中分子量分布的跟踪控制问题, 提出了一种简单的广义状态反馈控制方法, 实现给定分子量分布的跟踪. 该方法充分利用复合动态支持向量机模型, 实现分子量分布函数在时间域和空间域上的分离, 从而将分布函数的跟踪问题转化为动态权值向量的时间域跟踪问题, 并设计了状态反馈与积分器相结合的控制结构, 采用线性矩阵不等式技术对闭环系统稳定性和跟踪性能进行分析. 仿真结果表明该方法的可行性. |
| 英文摘要 |
| To track the molecular weight distribution in three-dimensional space, we propose a new method employing a generalized state-feedback controller. By the hybrid dynamic recurrent support-vector-machine model, the distribution function is effectively separated into aspects of time and space. Thus, the tracking of three-dimensional distribution will be transformed into a state-vector tracking in the time domain; and the control difficulty will be greatly reduced. A combination configuration of the state-feedback controller and the integrator is proposed, the linear matrix inequality techniques are employed to design the parameters; and the stability and tracking performances can be guaranteed simultaneously. Simulation results of a polymerization reaction process show the efficacy of the proposed method. |
