摘要：连续搅拌反应釜CSTR广泛应用于化工、燃料、制药等生产过程，由于其机理复杂、多变量耦合、非线性强，CSTR过程的常规控制难于取得理想效果。本文在一类通用的CSTR非线性机理模型基础上应用EMPC控制策略，针对不同生产场景定义了相应的优化指标。在考虑质量、安全等多种约束的条件下，直接基于非线性模型进行预测和优化，解决了CSTR过程的优化控制问题，并在多种控制模式下验证了控制算法的有效性。

Abstract: CSTR is widely used in chemical, fuel, pharmaceutical and other processes. Due to its complex mechanism, multivariable coupling and strong nonlinearity, traditional control of CSTR
is difficult to achieve ideal results. In this paper, based on a general CSTR nonlinear mechanism model, Economic Model Predictive Control (EMPC) control strategy is applied to define the corresponding optimization indexes for different production scenarios. Under the condition of considering the quality, safety and other constraints, the prediction and optimization are directly based on the nonlinear model, which solves the optimization control problem of CSTR process, and verifies the effectiveness of the control algorithm under various control modes.
