Optimal Surface Temperature Distribution and Control of Paper Machine Driers
-
摘要: 对于生产高级电容器纸的烘缸表面温度的最佳分布和最优控制的问题,本文用机理分析 和动态测试相结合的方法求得了数学模型;设计了前馈-反馈最优控制系统.经一年半的运 行,取得了满意的经济效果.本文提出的用常规仪表实现前馈-反馈最优控制的方法,实施方 便,应用可靠,具有实际意义.Abstract: Surface temperature control of paper machine driers used to produce 6μ capacitor paper is discussed in this paper. Mathematical model of the controlled plant is obtained by means of dynamic measurement and theoretical analysis. Besides, a feedforward-feedback optimal control system is designed and realized in the production line. This system has offered satisfactory economic and technical effect in operation for more than a year.
