【 摘 要 】

Expert system is essentially an intelligent computer program containing reasoning and knowledge, which uses the knowledge and experience of experts in a certain field to solve problems in this field. Expert control combines the concept and principle of expert system with automatic control technology, simulates the intelligence of experts, and realizes the control of the system. In actual production, because of the characteristics of time-varying, non-linear and large lag of single tank level parameters in liquid level system control, a novel expert PID intelligent control is proposed on the basis of traditional PID control in order to achieve the desired level value. According to the simulation results of METLAB, the expert PID intelligent control is superior to the traditional PID control in both dynamic performance index and practical application.
