Cognitive models based on self-reproduction are presented and built to improve the cognition of artificial fish,and high-level motion controls based on animal logic are implemented.Deterministic behavior models on copulation, spawning and environmental selection of artificial fish are built.It is shown by experiments that a high-level motion controller makes artificial fish adapt the virtual environment of sea and complete the process of life such as copula- tion,spawning,etc. KEY WORDS artificial life;artificial fish;self-reproduction;cognitive model;deterministic behavior;high-level motion control 架架架架架架架架架解架架架架架程解架醉架架架架架黎架邵架架能架解架架黎架架架程代架 (上接第547页) Compensating Tactics of Flatness Control for Hot Strip Mills SUN Kewen",HE Anrui",YANG Quan",ZHANG Oingdong,ZHAO Lin,GUO Xiaobo 1)National Engineering Research Center for Advanced Rolling,University of Science and Technology Beijing,Beijing 100083,China 2)Mechanical Engineering School,University of Science and Technology Beijing.Beijing 100083,China 3)Anshang Iron and Steel Group Co.,Anshang 114021,China ABSTRACT In the flatness control system of hot strip,measured flatness signals usually contains additional sig- nals caused by temperature difference along the lateral direction of the hot strip after rolling.The lateral temperature of the hot strip was measured by a kind of thermovision in ASP1700 hot strip mill in AnSteel,China.By analyzing the influence of the temperature differece on the flatness control system of hot strip,the lateral temperature field dis- tributing law was obtained based on the least square method and a temperature compensating model for the control target of strip flatness was set up at the same time.
