摘要
换热器广泛应用于建筑工程领域及工业过程中,其出口介质温度的有效控制是保证质量、节能和安全生产的重要条件,因此换热器出口水温的控制是过程控制中的重要课题;文章以西门子SMPT1000换热器温度控制系统为研究对象,建立基于虚拟仪器的智能温度控制平台;该平台在实现传统PID控制的基础上,又增加了智能控制算法,斯密斯控制和模糊控制;实验证明该智能控制平台具有修改参数简易方便、曲线准确的优点,具有良好的动静态特性,且市场应用价值高。
Long term practical utilities of the heat exchanger has been established extensively in construction engineering as well as industrial process.Existing challenges within this domain,consequently,lie in the effective controller design of the medium temperature of the outlet,which is the essential requirement in quality guarantee,energy conservation and safety production.To investigate the control issue of the water temperature of the heat exchanger outlet,in this paper,SMPT-1000 heat exchanger temperature control system is adopted as the research object to establish the intelligent temperature control platform using virtual instrument.The proposed platform is demonstrated usefully and effectively of being a benchmark for several control techniques,like PID control,Smith control and Fuzzy control,giving rise to a simpler modification of the system parameters,a more accurate demonstration of the curves as well as a higher potential value of the market application.
