【摘要】 与传统的序贯设计方法相比,过程工艺与控制系统的集成优化设计可较大地提高过程的可操作性和经济性能,但基于常规动态优化的集成设计问题求解困难。采用最优控制和分层优化策略的思想,将线性二次调节器(LQR)嵌入到过程工艺与控制系统集成设计框架中,以降低集成优化设计问题的求解难度。将该方法应用于连续搅拌釜式反应器(CSTR)的设计中,通过与传统的序贯设计方法相比较,表明了该方法的有效性。更多还原

【Abstract】 Compared with traditional sequential design methods,simultaneous design and control process may result in numerous economic and operability benefits. While the conventional integrated design problem on the basis of dynamic optimization is difficult to solve. In this paper,the linear quadratic regulator( LQR) is embedded into the framework of integrated design and control process. The proposed method is based on the optimal control and bi-level optimization strategy to avoid the complexity of integrated design and keep the problem size manageable. Finally,the proposed method is applied to a jacketed exothermic continuous stirred tank reactor( CSTR),by comparison with the traditional sequential design method. The results show that the proposed method is effective.更多还原
