Abstract:
To work in hazardous environment the popularity of mobile robot is increasing day
by day. DC motors are widely used to drive these mobile robots. To study the
dynamic response of a mobile robot the mathematical model of a DC motor was
made and simulated by SimApp software. Dynamic response of a second order
system and DC motor model were studied and simulated by using step input and P,
PI and PID control. From results of simulations and comparison between different
controllers only PID controller found most suitable to drive a mobile robot for speed
and position control. The simulated result was also verified with previous work and
this simulated result found similar to that of previous work. By using PID controller
the stability could reach quickly, without overshot and no residual error.
