This paper concerntrates on the analysis, design and control methodology in the machining servo system. The overall architecture of motion system is investigated to realize the drawbacks of traditional scheme. Then, this research proposes the suitable design of controller due to rapid calculation, high precision and friendly graphical user interface. The diagram of Fuzzy self-tuning PID and feedforward...
This paper presents the nonlinear modeling of Switched Reluctance Motor (SRM) using look up tables. The two lookup tables flux-current-angular position (λ- i - θ) and torque-current-angular position (T- i - θ) are formulated. The value of turn-on (θon) and turn-off (θoff) angles of power converter show considerable impact on the performance of SRM drive. The selection of suitable value of θon and...
This paper presents a method for improving the speed profile of a three phase induction motor in direct torque control (DTC) drive system using a proposed fuzzy logic based speed controller. A complete simulation of the conventional DTC and closed-loop for speed control of three phase induction motor was tested using well known Matlab/Simulink software package. The speed control of the induction motor...
This paper presents Adaptive Neuro-Fuzzy Inference System (ANFIS) based intelligent control of vector controlled induction motor drive. The proposed intelligent control scheme consists of sensorless adaptive neuro-fuzzy speed controller with speed estimation based on adaptive neuro-fuzzy inverse model. The proposed neuro-fuzzy speed controller incorporates fuzzy logic algorithm with a five-layer artificial...
This paper presents a comparison in efficiency between a fuzzy logic controller (FLC) and a proportional-integral (PI) controller based interior permanent magnet synchronous motor (IPMSM) drive incorporating an online loss minimization algorithm (LMA). The LMA is developed based on the motor model. In order to maximize the operating efficiency, the d-axis armature current is controlled optimally based...
