DESIGN A SPEED CONTROL OF DC MOTOR USING FUZZY LOGIC AND IMPLEMENT USING ATMEL IDS 6.0
AIM:
The aim of the project is to design a DC Motor using Fuzzy Logic using VHDL tools and implement it in programmable FPGA.
THEORY:
There are many conventional techniques for the Speed Control of DC motor. Some techniques like fuzzy control involve modeling of control of skins of a human expert and hence the present work is on a fuzzy based speed control strategy for DC motor. The control is implemented by coding the feedback of the motor to the V to F converter and then the decade counter. The control is done through the VHDL coding.
The line voltage, frequency and armature current are constantly monitored. Any deviation in the set speed generates proportionate error count that triggers the fuzzy logic speed control system and takes to regulate the speed by computing end loading defuzzified count.
HARDWARE:
The hardware of Speed Control of DC motor consists of ADC, FPGA as Fuzzy controller, SCR interfacing board and DC Shunt motor.
SOFTWARE:
Using VHDL software tool, a digital system can be designed and simulated. Also the timings of various signals can be verified. Then the system can be implemented in ATMEL FPGA using IDS 6.0.
