ABSTRACT

According to time-varying, large delay object characteristics of level system in the FESTO process control system, this paper introduces a new method to realize the fuzzy PID control through a combination of configuration software and ActiveX control. The experimental results showed that the response curve of fuzzy PID control system was smooth transition, fast response, high accuracy of regulation and good steady state performance. It could receive the good control effect and meet the requirements of industrial control. This method provided a new attempt and approach to the fusion of complex control algorithm and software in the distributed computer control field.
