FPGA Based Motorize Cooling

The aim of this paper is to control the speed of dc motor based on room temperature using pulse width Modulation technique with FPGA. To get rid of the problem of Obscurity to control temperature in industries and for the requirement of increasing flexibility and overall automation in the high systems performance, a FPGA is used as a controller. A temperature sensor built with thermistor along with series resistance which indicates the change in the voltage as the temperature changes and according to the change in voltage, speed of the motor is varied using pulse width modulation technique. The duty cycle is varied from 0 % to 100 % depending upon the variation in the room temperature. Smooth and efficient control of DC motor is obtained at 25 % to 100 %. It is easier, reliable and energy efficient. Hardware implementation is also done. The result of the research and output form has been investigated. Various design criteria, performance characteristics, comparison with different parameters have been plotted in MATLAB software system and other simulation results have been discussed in detail in this paper. The Proteus software 8.6 is used for circuit designing and ISIM Xilinx software is used to observe the variation in PWM.
