摘要 为了解决高纯内部热耦合精馏塔(ITCDIC)的强非线性特性给控制器的设计带来较大困难的问题,将非线性Wave理论运用到内部热耦合精馏塔的控制设计中.首先根据浓度曲线的特性提出了浓度波形的描述函数.其次根据波形描述函数以及物料守恒关系推导出波速公式.最后将Wave理论与一般模型控制(GMC)结合起来,建立了基于Wave模型的一般模型控制(WGMC).在苯-甲苯物系的实例研究中与传统的基于数据模型的一般模型控制(TGMC)进行比较.研究结果表明,WGMC在伺服控制和干扰控制的表现都明显优于TGMC,WGMC控制方案较传统的一般模型控制方案更加稳定可靠. Abstract: To solve the problem that highpurity internal thermally coupled distillation columns (ITCDIC) present strong nonlinear dynamics which troubles the controller design, nonlinear wave theory is introduced into the control design of ITCDIC. First, the describing function of the profile of concentration is proposed according to the characteristics of the concentration curve. Then, the wave velocity is derived from describing function of the concentration profile and component mass balance of each stage. Finally, combining the Wave model with the generic model control (GMC) a generic model control based on the Wave model (WGMC) is proposed. Compared with databased generic model control (TGMC) in benzenetoluene system, WGMC performs more excellently both in servo control and regulatory control and it is more stable and efficient than the generic model con trol scheme.
