| 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. | ||
