Advance Synchronization of Multiple Machines

In textile industry many processes required speed synchronization of more than one motors involved in the process. Speed control of motor is very important especially in the fields including industrial applications, robotics, textile mills, etc. In all these application motor speed synchronization is invigorate in conveyor belt driven by multiple motors. Sudden changes in load cause hunting and oscillatory behaviour in DC machine. This behaviour can be harmful to the process. There are so many methods which is used for controlling the DC machines. Among all these method master-slave synchronization is a widely used technique. So, speed control of DC motors at different load conditions is essential to achieve a robust system. The synchronization is done by using microcontroller chip which controls the master slave whose speed is followed by the other motors which all have to be synchronized. For PWM generation PIC microcontroller is used. The ADC is available in microcontroller chip which create feedback loop. This ADC checks the voltage level of the motor and accordingly the voltage level of the motor can be maintained at a fixed level. A driver circuit is used to drive the motor. Hence, a closed loop motor speed control circuit is designed and the total amount of power delivered to the motor is varied depending on load conditions. In this technique, the regulation of motors speed is achieved by changing the voltage of the motor which is adjusted by the duty cycle of PWM.
