Speed control of DC motor via Internet for Traction applications

In this paper, we report speed control of dc motor using android smart phone through Internet. Internet has become one of the irreplaceable tool for communication but in recent years it has gone a step ahead of controlling any machine which placed remotely. In the proposed system, the industrial machines like cranes, traction motors can be controlled remotely by just scrolling the widget in the android smart phone. This gives enough opportunities for physically challenged people to operate industrial machines more easily and safely. The proposed system is simple, cost effective and digital. The MATLAB and PROTEUS simulations confirmed the theoretical estimates of the performance of the proposed system.
