DC motor control based on embedded Linux

Currently, the motor controllers need various functions such as real time control and communication capabilities with remote host computer. This paper presents a communication TCP/IP module to control a DC motor. Pulse Width Modulation was employed so as to drive the motor at the desirable speed. the control of the motor via PID controller in order to maintain the desired speed regardless of load as well as the wireless Ethernet communication between the microcontroller and the PC. A Human Machine Interface program was made to supervise the motor´s speed performance and create a control unit to change the parameters.
