Abstract
This paper describes the design and implementation of a personal computer
based closed loop DC motor speed control system Using LabVIEW 8.5 Package
for data manipulation and interface control. Tuning the parameters of the PID
controller is done using trial and error method by conducting simulation on the
system model using Matlab package. This method is used to find the best system
response depending on the tuning parameters of the PID controller. These
parameters are then implemented in the designed real time digital PID controller
system based on LabVIEW package.
Carrying out the task of tuning the PID controller on the real time model requires
great effort and time consuming especially in the early stages. Thus the PID
controller tuning is firstly carried out on the simulation model in Matlab which is
time saving and gives close parameter approximation for applying in the real time
system directly. The PID control action in the real time system shows more
oscillation in comparison with the PID simulation control action. Simulation and
real time results for the speed control of the DC motor experiment were found to
have a high degree of agreement in maintaining the desired speed of the motor.
