—The objective of research was to present the closed loop speed controller of variable-voltage variable-frequency (VVVF) induction motor drive. The main issues regarding a Fuzzy PID controller were designed for controlling an induction motor. The proposed controller is composed the rule base with analysis two degree of freedom to fuzzy rule. The little fluctuation slope of rise time can be minimize with compensation Fuzzy and PID controllers. The study used LabVIEW program and adjustment of controller parameters were set consistently with the mathematic equation of the motor. In this study, the 0.375 kW model of three phase induction motor was used in the simulation. The results showed that the Fuzzy PID controller can drive the induction motor system more effectively with good tracking and found robust is suitable for controlling the system.
