大型炼油厂酮苯脱蜡过程的优化控制

本文通过对润滑油生产中酮苯脱蜡结晶过程的机理分析,建立了用于优化控制的数学模型,并以润滑油的收率最大为目标函数,采用复合形寻优法求得了对象的最优操作点.现场开环运行结果表明,收率至少提高2个百分点以上,可为企业带来较大的经济效益。     

离散大系统的比较原理在稳定性理论中的应用

In this paper, we establish the comparison principle of the discrete systems and study the decomposition problem in the theory of stability. At the same time the region of stability of a nonlinear time-invarant system is estimated as an example.
