Framework of Multi-agent Based Intelligent Control System for Ethylene Rectifier

As a typical multivariable system, ethylene rectifier is a very complicated system and these variables are connected seriously. Traditional control forms like PID and advanced process control (APC) are very difficult to realize its ideal control effect, they lack the capability to coordinate the variable relations. Analyzing the industry process characteristics and its control development conditions has put a multiagent control system for ethylene rectifier forward. In order to realize distributed intelligent control of the system, some questions about the system´s cooperation are inquired, and the necessity and feasibility of the system building are analyzed. In the end, the system´s structure is given
