摘　　要：针对复杂的精馏塔MIMO温控系统的多变量、非线性、强耦合的特点和自适应需求,设计了基于矩阵解耦精馏塔的VOFFLC系统。首先,对温控系统的多变量控制模型进行改进,利用矩阵解耦理论实现对角解耦,以此改变控制通道的特性;然后,设计基于矩阵解耦的精馏塔VOFFLC温控系统,实现精馏塔的塔顶和塔底的自适应温控;最后,采用仿真实验,对所设计的多种温控系统进行性能比较。实验结果表明,VOFFLC系统可以实现控制参数的自适应,具有更强的论域容错性和鲁棒性。For the complex rectifying column MIMO temperature control system multivariable, nonlinear,strong coupling characteristics and adaptive needs, the VOFFLC system based on a matrix decoupling rectifying column is designed. Firstly, the multivariable control model of the temperature control system is improved and the diagonal decoupling is realized by using matrix decoupling theory to change the control channel characteristics. Then, the VOFFLC temperature control system based on matrix decoupling is designed to realize the adaptive temperature control at the top and bottom of the rectifying column. Finally, simulation experiments are used to compare the performance of the designed multiple temperature control systems. The experimental results show that the VOFFLC system can realize the adaptive control parameters and has stronger theoretical domain fault tolerance and robustness.
