Abstract:
Microcontrollers are very useful for many
electronics control system. In today’s industries,
the DC motor speed control is a common practice.
In this paper, the drilling speed control (DSC)
system is presented. The purpose of the thesis is to
control the DC motor with Pulse-Width-
Modulation (PWM), generationmethod and
applied it to burst the materials by using
Peripheral Interface Controller (PIC)
microcontroller. In this system, tachometer is used
in a feedback signal to control the speed of the
system. The motor position control system depends
on manual touch switches. By using Proportional-
Integral-Derivative (PID) controller and PWM,
drilling speed can be controlled from slow
response to fast response. This system is not
depended of the load and is implemented by using
PIC16F877A and CCSCcompiler software.
