Abstract: This paper proposed a fuzzy logic controlling method which can improve the effect of PID type controller. The MATLAB/SIMULINK software was used to simulate comparison of step input response between the high-order non-delay control system and the second-order delay system, with the second-order delay system using traditional PID control and fuzzy PID control parameters respectively. As a result, it is found that the control effect of the parameters of high-order non-delayed system was significantly improved by adding fuzzy variable control.

Key words: fuzzy logic controller, PID control, SIMULINK models
