Abstract

For the problem needed to solve during the process of steel cycle power generation, a set of pressure regulating system driven by step motor was designed based on direct-drive volume control (DDVC). An incremental fuzzy PID controller was developed for this system. Then the dynamic characteristics were simulated in Matlab/simulink. The results show that: compared with the simulation curve controlled by traditional PID, this regulating system can achieve better performance by fuzzy PID.
