Speed Control of Three Phase Induction Motor Using PLC under Open and Closed Loop Condition

A Digital Phase Locked Loop Speed Control of Three Phase Induction Motor Drive: Performances Analysis

This paper deals with performance analysis and implementation of a three phase inverter fed induction motor (IM) drive system. The closed loop control scheme of the drive utilizes the Digital Phase Locked Loop (DPLL). The DPLL is safely implemented all around the well known integrated circuit DPLL 4046. An experimental verification is carried out on one kw scalar controlled IM system drives for...

Fuzzy Logic Speed Control of Three Phase Induction Motor Drive

This paper presents an intelligent speed control system based on fuzzy logic for a voltage source PWM inverter-fed indirect vector controlled induction motor drive. Traditional indirect vector control system of induction motor introduces conventional PI regulator in outer speed loop; it is proved that the low precision of the speed regulator debases the performance of the whole system. To overc...

A Wireless Speed Control of Three Phase Induction Motor

Induction motors are the widely used motors in largely power-driven home appliances, agricultural and industrial applications. Induction motors are largely used because of its advantages such as Simple and rugged design, low cost, low maintenance and direct connection to an AC power source. Many applications need variable speed operation and one of them is a simple fan load. The main aim of the...

FPGA-based Speed Control of Three-Phase Induction Motor

The field programmable gate array (FPGA) technology provides programmable system-on-chip (PSoC) environments for designing modern digital ASIC controllers for specific applications. This paper presents a FPGA based speed control IC for three-phase induction motor drives. The sinusoidal PWM is realized on a single FPGA chip from Xilinx Inc. to provide controlling switching pulses for inverter bl...
