The main core of this paper is to design a speed control system to control the Permanent Magnet DC (PMDC) Motor speed at desired speed (set point) through the technique of soft computing based self tuning of Proportional — Integral-Derivative controller which is designed in the platform of LabVIEW program, and the real — time Speed control of the DC motor was realized by using DAQ (Data Acquisition) device. The application of soft computing (Fuzzy Logic) to the PID controller imparts it the ability of tuning itself automatically in an on-line process while the application of LabVIEW to the PID controller makes it give an Desired Speed by searching for the best set of solutions for the PID parameters. Simulated results in LabVIEW using Fuzzy-PID toolkit and also the same has been implemented and tested for a 12 volt DC motor.
