摘　　要：通过对精馏塔的系统特性进行分析,确定了适宜的控制方案,采用稳态模拟技术确定了灵敏板,并进行稳态闭环测试,在此基础上确定了闭式热泵精馏系统的控制方案。文中运用动态模拟技术对确定的热泵精馏控制系统的动态特性进行分析。结果表明,当系统出现扰动时,本文提出的热泵精馏控制方案能够使系统快速达到新的稳态,方案可行,且具有较强的抗扰动能力。Suitable control scheme is determined by analyzing dynamic characteristics of the distillation column system. Location of the sensitive plate is found and steady state closed loop is tested with steady state simulation techniques. A control scheme for closed heat pump distillation is proposed based on steady state characteristics of distil- lation column. Dynamic characteristics of the control system are analyzed with dynamic simulation techniques. The resuits show that the proposed control scheme is feasible and the system can reach new steady state quickly when there is a disturbance, and the control system has good disturbance rejection capabilities.
