Vector control, also called fieldoriented control (FOC), is a Variable frequency Drive (VFD) control method in which the stator currents of a 3 phase induction motor are identified as two orthogonal components that can be visualized with a vector. The vector control of induction motors is one of the most suitable and popular speed control technique presently used. The vector control technique d...

The virtual instrumentation (Vl) concept has been applied to ac and dc type electric drives. The Visual Designer is used for a dc motor and the LabView is used for a three-phase, delta connected induction motor. The essential parameters such as the line current, phase voltage, torque and speed are monitored continuously while the machines are operating on load. The data obtained from the drive ...

Digital Simulation and implementation of a Power Factor Correction (PFC) half bridge converter based adjustable speed voltage controlled VSI fed PMBLDC motor is presented in this paper. A single-phase AC-DC converter topology based on the half bridge converter is employed for PFC which ensures near unity power factor over wide speed range. The proposed speed control scheme has the concept of DC...

-This scheme presents an integrated solution for Photo Voltaic cell(PV) fed water-pump drive machine which uses an Open-End Winding Induction Motor (OEWIM). The dual inverter fed OEWIM drive achieves the functionality of a three level inverter and needs low value DC bus voltage. This helps in optimal arrangement of Photo voltaic cells, this can avoid large strings and helps in improving the PV ...

In this paper, design of current controller for a two quadrant DC motor drive was proposed with the help of model order reduction technique. The calculation of current controller gain with some approximations in the conventional design process is replaced by proposed model order reduction method. The model order reduction technique proposed in this paper gives the better controller gain value f...

A stability criterion for universal fuzzy position control drives is described. This method allows an immediate definition of the stability boundaries through the knowledge of common motor parameters. The method can be applied to almost every type of motors, from DC to Synchronous, regardless of most fuzzy controller characteristics. “Elastic” fuzzy controller "gain" limits can be established a...

The paper presents simulation results of hybrid fuzzy logic with proportional plus conventional integral-derivative controller for the speed control of permanent magnet brushless dc (PMBLDC) motor. Although conventional PID controllers are widely used in the industry due to its simple control structure and ease of implementation, these controllers pose difficulties under the conditions of nonli...

This paper proposes to control the speed of the permanent magnet (PM) DC motor drive using fuzzy logic control (FLC) based on Matlab simulation environment. The proposed speed controller is developed based on fuzzy logic, to minimize maximum overshoot and steady state error. A comparison study and analysis of proposed fuzzy logic control to classical PID control system applied to PM DC motor is...
