COMPUTER BASED DC MICROMOTOR SPEED CONTROL SYSTEM

摘要

A computer based DC micromotor speed control system has been designed and fabricated. In the present study, a Data Acquisition Card has been designed for the measurement and control of DC micromotor (Minimotor 2230U 015S - 8400 rpm -Faulhaber DC motors, Switzerland). The comparative study of two controllers (PID & Improved PID) have been discussed for step response and load variations (magnetic brake). It is observed that the improved PID controller has better time response in terms of shorter rise time, settling time, no overshoots, undershoots and zero steady state errors than simple PED controller.
