| 摘 要： | 针对甲醛生产过程中氧醇比控制中大滞后延迟的难点,设计了改进的史密斯预估控制系统,并实现了对该系统的计算机仿真.通过调节热水阀门控制氧醇比不能彻底解决系统的大滞后问题,因此在调节器的设计上采用了史密斯预估控制算法,对系统的大滞后进行了补偿.同时又设计了模糊自校正控制,进一步提高控制系统的控制品质.

| Abstract: | An improved Smith predictive control method which can resolve the problem of a long time delay of the ratio of oxygen to methanol in the manufacturing process of formaldehyde is introduced,and the simulation of the system is also implemented.The delay problem can't be solved completely by adjusting valves,the Smith predictive control is then adopted in the design of the adjustment to make up for the long time delay.At the same time the fuzzy correct control is actualized to further improve the character of the control system. |

| Keywords: | the ratio of oxygen to methanol Smith predictive control fuzzy correct control parameter self-tuning system simulation |
